What will be the output of the program if the size of pointer is 4-bytes?

#include<stdio.h>

int main()
{
    printf("%d, %d\n", sizeof(NULL), sizeof(""));
    return 0;
}

A 2, 1

B 2, 2

C 4, 1

D 4, 2

ANS:A - 2, 1

In TurboC, the output will be 2, 1 because the size of the pointer is 2 bytes in 16-bit platform.

But in Linux, the output will be 4, 1 because the size of the pointer is 4 bytes.

This difference is due to the platform dependency of C compiler.
