Control Instructions - Programming

Q1:

What will be the output of the program? 
#include<stdio.h>
int main()
{
    int x = 3;
    float y = 3.0;
    if(x == y)
        printf('x and y are equal');
    else
        printf('x and y are not equal');
    return 0;
}

A x and y are equal

B x and y are not equal

C Unpredictable

D No output

ANS:A - x and y are equal

Step 1: int x = 3; here variable x is an integer type and initialized to '3'.
Step 2: float y = 3.0; here variable y is an float type and initialized to '3.0'
Step 3: if(x == y) here we are comparing if(3 == 3.0) hence this condition is satisfied.
Hence it prints 'x and y are equal'.
