Previous Year Question (PYQs)

The output of the following C++ Program is:
#include <stdio.h>
int main(void)
{
    int x, *p;
    x = 30;
    p = x;
    printf("%d", *p);
    return 0;
}




Solution

p is a pointer variable and must store the address of x, written as:


p = &x;


But the program assigns:


p = x;


which means an integer is assigned to a pointer, causing a compilation error (type mismatch).
