What if the user entered values less than or more than 5 times ??

In the code below the user is supposed to enter values 5 times so that the code runs, but if ( the case above ) ^^ is True, What happens ? int num = 1; int number; int total = 0; while (num <= 5) { cin >> number; total += number; num++; } cout << total << endl; }

If the user enters 5 values(smaller or bigger doesn't matters), the following code will return their sum. If the user entered only one value. Then because it is a loop statement it will take that value again and again. For Example:- If the input is 5. It will print 25.

If users enters a values less than 5. For example:- 5 and 10. It will go for a loop and first will add 5 to total and then 10. After that it will add the last entered number again till the loop ends. Therefore the following input will print 45.

So it will take it as the user entered the value 5 five times and gives 25 as the sum ...

The user can't put more then 5 numbers or less then 5 because that's how the code is written. Don't use the SoloLearn compiler it creates confusion get a desktop one
