Few Notes to remember:

  • * is used to access the value stored in the pointer variable
  • & is used to store the address of the given pointer

CODE

#include <stdio.h>

int main()
{
    
    int var = 24;   // actual variable declaration
    int *p;

    p = &var;   // storing address of int variable var in pointer p

    printf("\n\nAddress of var variable is: %x \n\n", &var);

    // address stored in pointer variable
    printf("\n\nAddress stored in pointer variable p is: %x", p);

    // access the value using the pointer variable
    printf("\n\nValue of var variable or the value stored at address p is   %d ", *p);

    return 0;
}

the output of above code is

Address of var variable is: 61ff18

Address stored in pointer variable p is: 61ff18

Value of var variable or the value stored at address p is   24
