Answer 1

num++ is a simple way to write "num=num+1"
It's a common piece of code often use in loops and everywhere you need a step-by-step increment of a int variable.
If you miss to increment the check value in a loop you can have your program stuck in an infinite loop
Example:

int x = 0;
while (x < 5) {
cout << x << endl;
// This and the next line are not executed
// x++;
}
