Programming Fundamentals/Practice: Pointers

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

Learning ObjectivesEdit

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. Acquire a general understanding of the pointer data type, the address and indirection operators, the concept of dereferencing.
  3. Given pseudocode, write the C++ code for a program that uses reference variables.

ExercisesEdit

Exercise 1Edit

Answer the following statements as either true or false:Edit

  1. The address operator is the @ symbol.
  2. Passing by reference should be used when there is only one item to be modified.
  3. Variables of pointer data type are defined using an asterisk.
  4. Using pointers with the indirection operator can be used instead of passing variables by reference.
  5. There are two kinds of dereferencing – one with the indirection operator and the other with the index operator.

Miscellaneous ItemsEdit

None at this time.

Lab AssignmentEdit

Creating a Folder or Sub-Folder for Chapter 22 FilesEdit

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_22 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)Edit

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_22_Pseudocode.txt

Detailed Lab InstructionsEdit

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

  • Create a source code file from the Lab_22_Pseudocode.txt file. Name it: Lab_22.cpp
  • 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.

ProblemsEdit

Problem 22a – InstructionsEdit

Give a general explanation of the pointer data type and the use of addresses and dereferencing. Include both the indirection operator and the index operator in your discussion.
