C Quiz – 109 | Question 4
  • Difficulty Level : Basic
  • Last Updated : 24 Oct, 2015

Find out the correct statement for the following program.




#include "stdio.h"
  
int * gPtr;
  
int main()
{
 int * lPtr = NULL;
  
 if(gPtr == lPtr)
 {
   printf("Equal!");
 }
 else
 {
  printf("Not Equal");
 }
  
 return 0;
}

(A) It’ll always print Equal.
(B) It’ll always print Not Equal.
(C) Since gPtr isn’t initialized in the program, it’ll print sometimes Equal and at other times Not Equal.


Answer: (A)

Explanation: It should be noted that global variables such gPtr (which is a global pointer to int) are initialized to ZERO. That’s why gPtr (which is a global pointer and initialized implicitly) and lPtr (which a is local pointer and initialized explicitly) would have same value i.e. correct answer is a.
