C Programming Me Data Types Kya Hota Hai

Data types used in c programming. C programming me data type’s kya hota hai, (डेटा टाइप्स In C प्रोग्रामिंग) iske kitane type’s hai, inka use kya hai ye sub hum is post me details me janane wale hai.

Data Types Kya Hai:

C programming me agar koi value variable me store karani hai to hume wo kis prakar ki value hai to pahale declare karana padata hai, taki compiler ko samaj me aaye ki humane program me kis tarah ki value ka use kiya hai.

Data yane set of values hota hai. Data types ek format hai jiska use hum specific value ko variable me store karane ke liye karate hai. Hume agar kisi value ko variable me store karana hai to hume usi prakar ka data types use karana padata hai.

C programming me data types ko main 4 category me divided kiya gaya hai. Aap niche image me dekh sakate hai.

1. Basic Data Type:

Basic data types ka mostly programming me use kiye jate hai. Ye data types mainly arithmetic calculation karane ke liye kiya jate hai.

Basic data types Ko sub category me divide kar sakate hai.

a) Integer

b) Floating

c) Character

a) Integer:

Ye data type numerical value (without decimal places) store karane ke liye use kiya jata hai.

Ise declare karane ke liye ‘int’ keyword ka use hota hai. Iske liye generally 2 bytes memory lagati hai. Integer data type ki range -32768 to 32767 hai.

e.g Hume kisi person ka age declare karana hai to

int age=20, is prakar hum declare kar sakate hai.

b) Floating:

Isme hum numerical value jo decimal place me hoti hai ye store karane ke liye hota hai.

Ise declare karane ke liye ‘float’ keyword ka use hota hai. Iske liye generally 4 bytes memory lagati hai.

Example:

Float a =10.2

Float price= 1001.52

c) Character:

Character data type alphabet, single character ko variable me store karane ke liye use kiya jata hai. Ye character single quote me use kiya jata hai.

Character data type ke liye ‘Char’ keyword use kiya jata hai. Isko 1 byte memory lagati hai.

Example:

Char name=’a’

2) User defined Data Type:

User defined data type yane jo user ne banaye gaye data type hai. Mainly 2 subcategory hai.

a) Structure:

Collection of similar as well as different data types.

b) Union:

Union bhi collection hota hai similar aur different data types ka.

   

3) Derived Data Types:

Derived data type yane is data type ko kisi aur data types ki help se create kiya gaya hai.

Niche diye gaye data types hai jo derived data types hai.

a) Array:

Array ye ek collection hota hai similar type of data elements ka.

b) Pointer:

Pointer ka kam hota hai variable ki memory location ko point karana.

4) Empty Data Type:

Empty data types ka program me waise to kuch use nahi hota hai. Ye sirf isliye use kiye jate hai taki function ka jo return type hota hai use empty dikhane ke liye.

Empty data type ko denote karane ke liye ‘Void’ keyword ka use hota hai.

Agar koi function kuch value return nahi karata hai to use void denote kiya jata hai.

Is tarah hum c programming me data types use karate hai. Agar aapko data types ke bare me koi problem ho to niche comment me bata sakate hai.

C Programming Me Variables Kya Hota Hai

C programming me variable kya hota hai (Variable इन C प्रोग्रामिंग) isse kaise declare kiya jata hai. C programming me variable declaration ka bahut hi importance hai. Iske bina hum koi bhi program write nahi kar sakate. Ye ek basic term hai isliye ye concept ko aapko understand karana hoga.

Variable Kya Hai?

Definition:    "Variable is nothing but a reserved memory block which is used to store different types of values and which value can change in execution of the program."

Variable yane reserved memory block hota hai jo kisi value ko store karane ke liye use ki jati hai. Simple bhasha me kaha jaye to variable yane Name hota hai.

Syntax For Variable Declaration:

Varible kaise declare kiye jate hai uska basic syntax hai.

Data Type Variable Name

Kisi bhi variable ko declare karane se pahale hume uska data type batana padata hai.

Example:

Int a,

Float price,

Is 2 example me int, float data types hai to wahi pe a, price ye variable ka name hai.

Variable Declare Karane Ke Rule:

C programming me variable declare karane ke liye kuch rule banaye gaye hai. Variable declare karate samay hume in rule ko follow karana padata hai.

1. Variable name not start with digit.

Variable name declare karate samay wo number se start nahi kar sakate.

2. Blank space now allowed.

Variable name me blank space allowed nahi hai.

3. White spaces now allowed.

Variable name me white spaces allowed nahi hai.

4. Variable name not be Keyword.

Variable ka jo name hai wo keyword nahi hona chahiye.

5. It is case sensitive

Variable ka jo name hai wo case sensitive hai.

E.g.

Int PRICE,

Int price

ye 2 alag alag variable hai.

Variable Ke Types

Variable ke 2 type’s hai.

1. Local Variable:

2. Global Variable:

1. Local Variable:

Local yane hum jis block me declare karate hai wahi iska use kar sakate hai. Agar humane isko kisi function me declare kiya to wo sirf usi function me use kar sakate hai.

Local variable ko hum value assign karani padati hai system ise default value assign nahi karati.

2. Global Variable:

Global yane hum is variable ko overall program me kahi bhi use kar sakate hai. Global variable ko default value system initialize karati hai.

Agar aap kisi variable global declare karate hai to aap usse kisi bhi function me kitane bhi times use kar sakate hai.

Variable Ko Program Me Kaise Use Karate Hai:

/* Program for understanding variable */

#include <stdio.h>

#include<conio.h>

Void main()

{

Int a=10, b=20,add;

Add=a+b;

Printf(“/n addition =%d, add)

Getch();

}

Upar diye gaye program me humane variable a, b, aur add inka use kiya hai jiska data type integer hai.

Example of Variable:

Int a;

Float salary;

Char c, ch;

To is tarah hum koi bhi variable simple tarike se declare kar sakate hai. Agar aapko kuch problem ho to aap comment ke jariye humare sath share kar sakate hai.

   scanf("%d %d %d", &N1, &N2, &N3 ) ;

   if(N1 > N2)

   {

      if(N1 > N3)

      {

         printf("\n Largest Number is %d", N1);

      }

      else

      {

         printf("\n Largest Number is %d", N3);

      }

   }

   else

   {

      if(N2 > N3)

      {

         printf("\n Largest Number is %d", N2);

      }

      else

      {

         printf("\n Largest Number is %d", N3);

      }

   }

C Programming For Beginner, Introduction

C Programming For Beginner, C Language kya hai, C Language ka introduction hindi me, history of C, ye sab baate hum is post me janenge. C language kisane invent ki ye bhi aapko is post me read karane ko milaga.

Dosto jin logo ko programming language sikhana hai unke liye ye ek accha awasar hai kyon ki kayi log hai jine programming language sikhana hai par English week hone ke karan wo jara hichakate hai. To unke liye maine hindi me programming language ka tutorial start kiya hai aapko yaha pe sabhi basic sikhane ko milega.

History Of C:

C programming language hai jiska invention Dennis Ritchie ne AT & T Bell Labs me USA me kiya tha. C Language inti purani hai phir bhi aaj ye bahut popular hai.

C language banane ke liye kafi sari languages ka bhi use kiya gaya jaise BPCL, B.

BPCL, B yesi kuch languages pahale se hi maujud thi par inme kuch limitation the. Lekin C language me kafi tarah ke data types hai.

Importance Of C:

C language ka kya importance hai.

1. C language ka use operating system develope karane ke liye hota hai.

e.g. Unix, Linux aur Windows etc.

2. C programming language kea ur bhi kuch fayade hai, jine banane ke liye C ka use hota hai.

Jaise Text editors, Compilers, Data bases etc.

3. C language ka use Game create karane ke liye hota hai.

4. System software as well as application software dono bana sakate hai.

Charactertics of C:

C programming isliye aaj bhi itni popular hi kyon ki

1. Ye easy aur simple hai sikhane ke liye

2. Structured language hai.

3. Iske program kisi bhi platform par easily execute kar sakate hai. Chahe wo windows ho, Linux ya Unix ho.

C Program:

C language ek structured programming language hai jiska code 4-5 lines se lekar 1000 lines tak ka ho sakata hai. Program ki coding aap kis prakar ka software bana rahe hai uspe depend hai.

C Compiler:

Hume C programming sikhane ke liye compiler ki jaruarat hoti hai. Jo ek software hota hai.

Compiler ka kam ye hota hai ki wo high level language ko machine language me convert karata hai. Hum jab program likhate hai usse sirf hum read kar sakate hai lekin computer usse samaj nahi sakata compiler ka yahi kam hota hai ki is code ko convert karake machine level language me karata hai.

C program ka extension ‘.c’ hota hai.

Internet par free compiler milenge jiski madad se hum C program ko execute kar sakate hai.

Mai apni aane wali post me aapko bataunga ki kaise hum c compiler ko windows 7 par install kar sakate hai.

Structure of C Programming:

C program wirte karane ke liye ek structure ko follow karana padata hai. C program ka structure kuch niche ki tarah hota hai.

   1.  Documentation section

   2.  Link section

   3.  Definition section

   4.  Global declaration section

   5.  Main function section

   6.  Subprogram section

1. Documentation section: Isko optinally use kiya jata hai iska hona na hona kuch farak nahi padata hai. Isme aap program ka naam, author ka naam aur other details isme likhane hote hai.

e.g. /* program for addition */

2. Link Section: Isme header files hoti hai jo compiler to library files se connect karata hai.

e.g.

# include <stdio.h>

#include <conio.h>

3. Definition Section:

Isme sabhi constant declare karane hote hai.

e.g. # define pi 3.14

4. Global declaration:

Agar aapko koi variable ek se jayada function me use karane hai to aap usko globally declare kar sakate hai.

5. Main Function:

 Aapka jo main program hota hai wo yaha pe hota hai. isme different variable declaration aate hai. sabhi program ka code aata hai.

6. Sub program Section:

Isme all user defined function hote hai to main function me call kiye jate hai.

Ye simple C program ka structure hai jab aap koi program execute karoge to apne aap aapke samaj me ye aa jayega.

Aasha karata hu ki aapko ye post acchi lagi hogi agar aapko iske related koi problem ho to comment me jarur bataye.

C Compiler: Compile Run C Program On Windows 7, 8 32 Bit And 64 Bit

C Language in Hindi. Aap C programming to sikhana chahate to aapko c program compile, run karane ke liye Turbo C software ki jarurat padati hai. Windows 7, 8 in operating system ke liye Turbo C software hai jiski madad se aap program run kar sakate hai.

Mai is post me aapko bataunga ki kaise hum kisi bhi operating system me chahe wo windows 7, 8 inme 32 bit ya phir 64 bit hai to bhi koi problem nahi hoga. Pahale kya hota tha windows 7,8 me C program ko run karane me bahut problem aati thi par ab uske liye Turbo C software available hai ji windows 7,8 ke bikul fit hota hai.

Turbo C Download Aur Install Kaise Kare:

Step 1:

Aapko software download karane ke liye niche di gayi link pe jana hai aur software download karana hai.

Software: Setup_TurboC_7_v2.1.rar (Download Link)

Step 2:

Software download karane ke bad software ko extract kare. Extract karane ke bad jo .exe file hai uspe double click kare. Aur software install karle.

Step 3:

Ab software install ho gaya hai ab start menu me se turbo c ko start karle.

First Program Kaise Run Kare:

Ab aapko C programming me first program likhana hai aaj hum sirf chota sa program dekhenge.

Step 1:

Turbo C software open kare. Phir menu me se file me click kare aur new file select kare.

Step 2:

Ab program wirte kare maine niche jo program diya usse simple copy karle.


/*program for the print hello world*/ #include<stdio.h> #include<conio.h> Void main () { printf(“/n Hello World”); getch (); }

Step 3:

Ab program ko compile kare compile karane ke liye menu me se compile option pe click kare. Agar koi error aa raha hai to usse solve kare.

Step 4:

Menu me se run pe click kare. Aapko program ka output dikhayi dega.

Program Ko Understand Karate Hai:

/*program for the print hello world*/                       

#include<stdio.h>

#include<conio.h>

Void main ()

{

printf(“/n Hello World”);

getch ();

}

Starting me jo humane /* */

iske bich me program ka jo name likha hai wo comment section hai isme hum kuch bhi likhe compiler isko ignore kar deta hai. Ye sirf humare understanding ke liye hota hai.

Uske bad #include stdio.h, aur # include conio.h

ye jo code hai isko file inclusion kaha jata hai ye files isliye jaruri hoti kyon hi hum program me printf, scanf function use karate hai uskeliye ye files compulsory hoti hai.

Void Main ()

Ye ek main function hai program me ek to main function hona jaruri hai.

Agar aap program me int main (), int main (void) use karate hai to aapko function ko zero value return karani padati hai aur uske liye hum return 0 use karate hai.

Jab hum Void Main () use karate hai tab hume getch () function ka use karana padata hai.

Printf:

Ye ek output function hai aap jo bhi is function me likhoge wo aapko program run karane ke bad display hota hai.

“/n”:

Iska use code ka output ko new line me display karane ke liye kiya jata hai.

Turbo C software ki help se aap koi bhi program run kar sakate hai. Agar aapko software install karane me koi problem aa rahi hai to comment me jarur bataye taki mai us problem ko solve kar saku.
