Why Include Headers Instead of C Source Files in Your Code?

Understanding the Error: Including C Source Files vs. Using Headers

In your grading assignment, you received deductions for including ".cpp" files instead of linking them. This indicates that your code exhibited improper software design practices.

The Purpose of Header Files

In C , header files serve as declarations for classes, functions, and variables. They provide the compiler with information about the interface of these elements, without including their implementation details. By separating headers from source files (.cpp), you:

1. Enhance code readability and maintainability.
2. Promote modularity by allowing different developers to work on distinct parts of the codebase.
3. Reduce compilation time by only including the necessary declarations.

Consequences of Including Source Files

By including ".cpp" files, you inadvertently:

1. Duplicated code, which can lead to bugs and maintenance issues.
2. Increased compile time since the entire implementation is copied into each file that includes it.
3. Limited code decoupling and flexibility, making it harder to modify code independently.

Proper C Development Practices

To address this issue, you should:

• Create header files that contain class and function declarations, as well as other essential interface information.
• Separate the implementation of these components into ".cpp" files, which are then included by the corresponding headers.
• Link these object files together to form a complete executable program.

By adhering to these best practices, you will improve the quality and maintainability of your C code.
