How to Link Two C Source Files

In C language, two source files can be linked together by following these steps:

1. Create two source files, for example file1.c and file2.c.
2. When you need to reference a function or variable from another file, you can use the extern keyword to declare the existence of these functions or variables. For example, in file1.c, you can declare functions from file2.c like this:

extern void myFunction();

1. Compile two source files to generate corresponding object files, such as file1.o and file2.o.
2. Combine two object files using a linker to generate an executable file. For example, you can use the following command in the command line for linking:

gcc -o myProgram file1.o file2.o

By doing this, you can link two source files together and generate an executable file.
