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

Correct option is D

The program will result in an error because p = x; is incorrect. p is a pointer, and it should be assigned the address of x, not its value. The correct assignment should be p = &x;. As written, the program tries to assign an integer value to a pointer, which is invalid and will cause a compilation error.
