Question

C++ Visual Studios

How many times will "!" print?

int i = -5

while(-5 <= i <= 0)

{

cout << "!";

--i;

}

Answer 1

The code will be as follows

#include<iostream>
using namespace std;
int main()
{
    int i = -5;
    while(-5 <= i && i <=0)
    {
        cout << "!";
        --i;
    }
}

Now, "!" will be printed 1 time

because for the 1st time i = -5 and the condition in the while loop satisfies, condition is true, the statements inside loop execute. so, "!" will print then i will decrement by 1, therefore for the next iteration (2nd) i = -6 and the condition in the while loop fails. since -5 is not less than or equals to -6 (-5 <= i fails) so, statements inside loop will not execute.

The code and output in Visual Studio

Answer: "!" will be printed 1 time.
