C Program to Find Address Locations of Variables

Address locations are usually represented with variable names. All the program must be loaded to memory, called RAM before execution by CPU. 

We can find memory address by using a format specifier %u

Let us see the code to find the address of a specific variable in C.

#include<stdio.h>
int main()
{
    char a;
    int x;
    float p,q;

    a='a';
    x=125;
    p=10.25,q=18.76;

    printf("%c is stored at address %u\n",a,&a);
    printf("%d is stored at address %u\n",x,&x);
    printf("%f is stored at address %u\n",p,&p);
    printf("%f is stored at address %u\n",q,&q);
    return 0;
}

In the above program,

Character format specifier is %c

Integer format specifier is %d or %i

float format specifier is %f

OUTPUT:

a is stored at address 2686751
125 is stored at address 2686744
10.250000 is stored at address 2686740
18.760000 is stored at address 2686736
