Previous Year Question (PYQs)

What is the output?

#include <stdio.h>
void main(){
  int **ptr;
  int temp = 65;
  ptr[0] = &temp;
  printf("%d", ptr[0][0]);
}




Solution

Explanation: The pointer ptr is uninitialized, so it does not point to valid memory. When the code tries to access ptr[0], it attempts to dereference an invalid location. This leads to undefined behavior, and in most cases results in a segmentation fault.
