LESSON 149 OF 667 · WHILE LOOPS & FOR LOOPS

For Loops: Printing Numbers in C++

Practice

We can achieve many different outcomes with for loops.

It's all about tuning the initialization, condition and iteration statements.

For example, we can print all numbers from 2 through 6:

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

The output of this code is:

2
3
4
5
6

Let's break down this code:

  • The initialization statement is int i = 2, so we start iterating from number 2.

  • The condition statement is i < 7. We could've written i <= 6 and it would still be correct.

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


Assignment

Let's print all numbers from 3 through 10 using a for loop.
