# Example: Measuring Time Complexity of a Single Loop Algorithm

In this lesson, we are going to learn how to compute the time complexity of an algorithm that involves a for loop.

## We'll cover the following

In the previous lesson, we calculated the time complexity of the algorithm implemented in a simple C++ program.

## A For Loop With `n`

Iterations #

Now, letâ€™s consider what happens when a loop is involved. Consider the following C++ program::
