Question

I have to write the output without using a computer.

What is the output of the following code?

int x = 9;

while (x > 0) {

if( x > 6 || x % 5)

cout << "x == " << x << endl;

x -= 2;

}

cout << "x == " << x << endl;

I know that the answer is:

x == 9

x == 7

x == 3

x == 1

x == -1

I ran it and that is the output.

Can you explain why x == 5 was not on the output? Maybe it has something to do with x % 5.

I know that the modulus sign gives the remainder! But in this case it just say x % 5 and the examples that i saw it always had something like x % 5 == 0.

In this case it is not comparing it to anything. Please explain in details so i can learn and see what i am doing wrong.

Explanation / Answer

if condition will only execute when the conditions are true ,here we have if( x > 6 || x % 5) i.e either x should be greater than 6 or x % 5 must not give 0.

in case of x=5 both conditions are false hence if statement has not been executed resulting you would not able to see x==5.

Note:Please do ask in case of any doubt,thanks.
