Using a Counter-Controlled while Loop in C++

Using a Counter-Controlled while Loop

Summary

In this lab, you use a counter-controlled while loop in a C++ program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements.

Instructions

Ensure the source code file named Multiply.cpp is open in the code editor.

Write a counter-controlled while loop that uses the loop control variable to take on the values 0 through 10. Remember to initialize the loop control variable before the program enters the loop.

In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop.

Execute the program by clicking the Run button. Record the output of this program.
