Expressions - Programming

Q1:

What will be the output of the program? 
#include<stdio.h>
int main()
{
    int k, num=30;
    k = (num>5 ? (num <=10 ? 100 : 200): 500);
    printf('%d\n', num);
    return 0;
}

A 200

B 30

C 100

D 500

ANS:A - 200

Step 1: int k, num=30; here variable k and num are declared as an integer type and variable num is initialized to '30'.
Step 2: k = (num>5 ? (num <=10 ? 100 : 200): 500); This statement does not affect the output of the program. Because we are going to print the variable num in the next statement. So, we skip this statement.
Step 3: printf('%d\n', num); It prints the value of variable num '30'
Step 3: Hence the output of the program is '30'
