namespace file linking c++

To link files in C++, you need to follow these steps:

1. Create multiple source files: Start by creating multiple source files with the ".cpp" extension. Each source file will contain a different function or class definition.

2. Use the "header" file: Create a header file with the ".h" extension. This header file will contain the function prototypes and class declarations that are defined in the source files.

3. Include the header file: In each source file, include the header file using the "#include" preprocessor directive. This ensures that the functions and classes declared in the header file are available in the source file.

4. Compile the source files: Compile each source file separately using a C++ compiler. This will generate separate object files for each source file.

5. Link the object files: Once all the source files are compiled, use the C++ linker to link the object files together. The linker combines the object files and resolves any external references between them.

6. Create the executable: After the linking process is complete, the linker will generate an executable file that can be run on the target platform.

By following these steps, you can effectively link multiple source files in C++.
