This is a simple program that prints the address of a variable in C programming language.

In the main function, an integer variable,a is defined.

Using the ampersand (&) operator, its address is printed.
The format specifier %p is used to print the address of the variable a.

#include <stdio.h>
int main(void)
{ 
    int a; 
    printf("Address of a: %p\n", &a);
    return 0;
}

The output will print the address of the variable, a in hexadecimal format. The address printed may be different in different execution cycles.
