Pointer in c in Hindi – C Pointer Example in Hindi

Pointer in c in Hindi :- C Pointer in Hindi Vo Variables Hote Hai Jo Dusre Variables ke Address ko store karte hai | Jesa ki aapko pta hai ki har variable ka memory me ek unique address hota hai | ye address hexa decimal form mei hota hai | isliye is address ko aap kisi bhi normal variable me store nhi kar sakte hai |

Pointer Basics

Kisi bhi Variable ke address ko store karwane ke liye aap pointer variable create karte hai | for example aap man lijiye aapne ek variable create kiya hai | is variable ka name Student_Age hai or aapne isme 30 value assign karwayi hai | to is variable ki memory mei location (address) 50F hai | ab yadi aap chahe to is address ko ek pointer variable me store karva sakte hai |

Pointer in C in Hindi

for example

int student_age,*pointer_var;

Student_age = 30
pointer_var = &Student_age

Pointer in c in Hindi ko samanjh ne ke liye ham examples ko dekhte hai.

Pointer in c programming with examples

Advantages of Pointer  

• Pointers ki help se aap dynamically memory allocate kar sakte hai|
• Pointers ki help se aap data structures ( linked-list,stack, queue) create kar sakte hai|
• Pointers ki help se aap Function se ek se jyada values return kar sakte hai |
• pointers ki help se argument passing ke douran aap variable ki copy ke badle original variable par kam kar sakte hai|
• pointers istemal karne se program ka execution time kam ho jata hai |
• Pointers ke duvara large data ko search or sort karna bahut aashan hota hai|

Using Pointers

Declaring  Pointers 

C me pointers ko declare karne ke liye sabse pahle aap data type declare karte hai | Esa lsliye kiya jata hai kyoki int type ka pointer varaible keval int type ke variables ka hi address store kar sakta hai |

data_type *pointer_name;

• Data_type Matlab Like Int , float
• Aap Asterisk(*) operator ko pointers declare karne ke liye istemal karte hai |
• Iskebad pointer variable ka name declare karte hai

Initializing Pointers 

C Programing me pointers initialize karne ke liye sabse pahle aap pointer variable ko likhte hai | ( Initialization part mei pointer variable ko bina asterisk operator (*) ke likha jata hai |

pntr_variable = &variable_name;

Iske bad aap ampersand operator yani address(&) (ise address of operator bhi kaha jata hai ) define karte hai | is operator ke bad aap bina koi space diye variable ka name likhte hai

Example 1:

#include<stdio.h>
int main()
{
    int age = 33;
    int *pntr;
    pntr = &age;
 
    printf(“Address of age variable is : %d”,pntr);
    
    printf(“Value of age variable is : %d”,*pntr);
}

Aap Uper Diye gye pointers output ke duvara ek variable ka address or uski value print karwayi gyi hai|

Output:

Address of age variables is : -1074204644;
Value of age variables is : 33 

Pointer to Structure

Structure variables ke pointers bhi create kiye ja sakte hai | ye usi tarah create kiye jate hai jese ki aap kisi normal varable ke pointers create karte hai |

Example 2:

#include<stdio.h>
 

/* Employee structure declaration */
struct Employee
{
    int Id;
    int Phone;
};

int main()
{

   /* Creating variable of Employee structure */
   struct Employee e1;
 
   struct Employee *emp;

   emp = &e1;

   emp->Id=101;
   emp->Phone = 237434839;

   printf(“Employee Id : %dn”,emp->Id);
   printf(“Employee Phone : %dn”,emp->Phone);

   return 0;
}

Output :

Employee Id : 101
Employee Phone : 2374334839

Pointers and Strings

Ham Example 3 me dikhte hai ki ham string ko pointers se kese print karate hai |

Example 3:

#include <stdio.h>
int main()
{
    char str[100];
    char *p;

    printf("Enter any string: ");
    fgets(str, 100, stdin);

    p=str;

    printf("The input string is: ");
  
    while(*p!='\0')
        printf("%c",*p++);

    return 0;
}

Output:

Enter any string: Masterprograming
The input string is: Masterprograming

Pointers and arrays

Ham Example 4 me dikhte hai ki ham Arrays ko pointers mei kese istemal karte hai | ye program ham simple tarah se dekhte hai |

Example 4:

#include<stdio.h> 

int main() 
{ 
int arr[5] = { 1, 2, 3, 4, 5 }; 
int *ptr = arr; 

printf("%p\n", ptr); 
return 0; 
} 

Output:

0x7ffd4f212230

Aap Uper diye output ko dekh sakte hai isme hamne keval array ka address print karaya hai |

• For Loop
• While and Do-While
• Creating and using Arrays
• Defining Functions
• Defining a String
