Answer:
The statement can be written as
int result = cube(4);
Explanation:
A function is a block of reusable codes to perform some tasks. For example, the function in the question is to calculate the cube of a number.
A function can also operate on one or more input value (argument) and return a result. The <em>cube </em>function in the question accept one input value through its parameter <em>number </em>and the <em>number</em> will be multiplied by itself twice and return the result.
To call a function, just simply write the function name followed with parenthesis (e.g. <em>cube()</em>). Within the parenthesis, we can include zero or one or more than one values as argument(s) (e.g. <em>cube(4)</em>).
We can then use the "=" operator to assign the return output of the function to a variable (e.g. <em>int result = cube(4)</em>)
