# Exercise 2: Computing Cubes

Let's compute cubes of variables using functions.

## We'll cover the following

## Problem Statement

Write a *function* `void computeCubes`

which:

- takes three integers
`num1`

,`num2`

,`num3`

as input. - computes the
**cube**of all**three**values.

This function is `void`

type hence doesn’t *return* any values. How will you get the updated values of `num1`

, `num2`

and `num3`

?? Hmmmm…

Hint:Thinks in terms of the pass by reference method of passing values.

### Example

**Input:**

```
num1=4,num2=2,num3=5;
```
