ISRO | ISRO CS 2013 | Question 62

Consider the following C code.
#include

#include 
void main()
{
 double pi = 3.1415926535;
 int a = 1;
 int i;
 for(i=0; i 
What would the program print?
(A) 000
(B) 010
(C) 101
(D) 111

Answer: (C) 
Explanation: In first iteration: i = 0:

a = cos(pi * 0/2)

a = cos(0) = 1, condition true print 1

Second iteration: i = 1

a = cos (pi/2)

a = 0, so else part would print 0

Third iteration: i = 2

a = cos(pi)

a = -1, since any value other than 0

inside if statement returns true,

print 1

Output: 101
Option (C) is correct.
