Answer 1

This is a SoloLearn's specific. You must enter input once before execution and watch results. Try your code on real IDE

Answer 2

So, yes. Code is correct

Answer 3

What do you mean? It correctly parses input "0 0 0 7" and using negative nums cause same behavior

Answer 4

And what do you what? Do you want to run code again for second positive integer within next line of input per one execution?

Answer 5

Shouldn’t it be obvious I just want a while(cin>>var) loop to work properly? If the user keeps inputting non-positive integers, the code should ask them to keep inputting until they input a positive integer or non-integer value.

Answer 6

It just doesn’t go as expected...

Answer 7

It doesn’t prompt me to enter another number if I give a non-positive one, it just ends the whole execution.

Answer 8

while statement expects to evaluate a true/non-zero-value or false/zero-value. What does (cin >> a) returns, if anything? Why not make it easier on yourself with the following:

while(true) {
cin >> a;
if (a < 0)
...
else
break;
}

Thank you guys.
