Scenario/Summary
This week, we learn how to manage complexity by putting together a ready-built application that comprises a number of separate header and source files. Our job here will be to take these individual files and combine them into one standalone application. Although the process is quite a simple one, it will emphasize the advantage of modularity when writing code. It also shows how code can be reused between programmers and/or applications.
STEP 1: Create the Project
Create a new C++ console-based project.
STEP 2: Add Files to Your Project
Unzip the source code and header files found in the Files section of the Course Menu Doc (Lab_7_files.zip), and then add these files to your project as needed.
STEP 3: Build and Test
Build your project (compile your program).
Eliminate all syntax errors.
Run the program.
STEP 4: Label Title
Capture a screen print of your output [Do a PRINT SCREEN and paste into an MS Word document.]
This is a sample program output:
Zip your project files.
Submit the Word document with screen print and zip file for grading.
files
on c++ you need to create a project and add the 5 files in the zip file.
Create the Project
Create a new C++ console-based project.
