Question

What is the output of the following program? Write your answer with explanation.

Answer 1

Answer:

Predict the output of below programs.

Question 1

#include<stdio.h>

int main()

{

   int n;

   for(n = 7; n!=0; n--)

     printf("n = %d", n--);

   getchar();

   return 0;

}

Output:Above program goes in infinite loop because n is never zero when loop condition (n != 0) is checked.

Question 2

#include<stdio.h>

int main()

{

   printf("%x", -1<<1);

   getchar();

   return 0;

}

Output is dependent on the compiler. For 32 bit compiler it would be fffffffe and for 16 bit it would be fffe.
