Practice 15: Counting Loops

Module by: Kenneth Leroy Busbee. E-mail the author

Summary: Questions, exercises, problems, etc. that support this chapter in the "Programming Fundamentals - A Modular Structured Approach using C++" collection/textbook.

Learning Objectives

With 100% accuracy during a: memory building activity, exercises, lab assignment, problems, or timed quiz/exam; the student is expected to:

  1. Define the terms on the definitions as listed in the modules associated with this chapter.
  2. Identify which selection control structures are commonly used a counting loops.
  3. Be able to write pseudo code or flowcharting for the for control structure.
  4. Be able to write C++ source code for a for control structure.
  5. When feasible, be able to convert C++ source code from while loop acting like a counting loop to a for loop and and vice versa.

Memory Building Activities

Exercises

Exercise 1

Answer the following statements as either true or false:

  1. Only for loops can be counting loops.
  2. The integer data type has modular arithmetic attributes.
  3. The escape code of \n is part of formatting output.
  4. Nested for loops is not allowed in the C++ programming language.
  5. Counting loops use all four of the loop attributes.

Solution

Answers:
  1. false
  2. true
  3. true
  4. false
  5. true

Miscellaneous Items

None at this time.

Lab Assignment

Creating a Folder or Sub-Folder for Chapter 15 Files

Depending on your compiler/IDE, you should decide where to download and store source code files for processing. Prudence dictates that you create these folders as needed prior to downloading source code files. A suggested sub-folder for the Bloodshed Dev-C++ 5 compiler/IDE might be named:

  • Chapter_15 within the folder named: Cpp_Source_Code_Files

If you have not done so, please create the folder(s) and/or sub-folder(s) as appropriate.

Download the Lab File(s)

Download and store the following file(s) to your storage device in the appropriate folder(s). You may need to right click on the link and select "Save Target As" in order to download the file.

Download from Connexions: Lab_15a.cpp

Detailed Lab Instructions

Read and follow the directions below carefully, and perform the steps in the order listed.

  • Compile and run the Lab_15a.cpp source code file. Understand how it works.
  • Copy the source code file Lab_15a.cpp naming it: Lab_15b.cpp
  • Convert the code that is counting (all four attributes) to a for loop.
  • Build (compile and run) your program.
  • After you have successfully written this program, if you are taking this course for college credit, follow the instructions from your professor/instructor for submitting it for grading.

Problems

Problem 15a – Instructions

Using proper C++ syntax, convert the following for loop to a while loop.

Example 1: C++ source code


for (x = 0; x < 10; x++)
  {
  cout << "Having fun!";
  }
