Chapter 6: Problem 34

A program contains the following function. int cube(int num) { return num * num * num; } Write a statement that passes the value 4 to this function and assigns its return value to the variable result.

Short Answer

Expert verified
Answer: The value of the variable "result" will be 64, as the cube function will calculate the cube of the input (4 * 4 * 4 = 64).

Step by step solution

01

Declare a variable result

First, we need to declare an integer variable named "result" to store the output of the function. To declare the variable, use the following code: `int result;`.
02

Call the cube function with input 4

Next, we need to call the cube function with an input value of 4. To do this, use the following code: `result = cube(4);`. This will call the cube function, passing it the value 4, and assign the returned result to the variable "result".
