Question

Now this is a silly puzzle I got from some exam paper,sadly I am unable to figure it out from last 15 minutes.

#include <stdio.h>

int main(void){

    /* <something> */    

      putchar(*(wer[1]+1));
   return 0;
 }

What should we replace in place of something in order to get the output e.Now we know putchar takes a int as argument but this code assumes to give a pointer.Does this question is even valid ?

Answer 1

Since a[i] is the same as *(a + i) by definition, you can transform the putchar() argument into wer[1][1]. So, something like char *wer[2] would be a satisfactory definition, and any values such that wer[1][1] == 'e' will work.
