Looping In Reverse in C++

A for loop can also count backwards, as long as we define the right conditions. For example:

for (int i = 7; i > 2; i--) {
	cout << i << endl;
}

The output of this code is:

7
6
5
4
3

Let's break down this code:

• The initialization statement is int i = 7, so we start iterating from number 7.

• We loop as long as i > 2, so we'll end at number 3. We could've written i >= 3 and it would still be correct.

• The iteration statement is i--, so we decrease our number by 1 every time.

Assignment

Let's print all numbers from 5 through -5 in decreasing order.
