make a function makefile

To create a makefile in C, you can follow these steps:

1. Open a text editor and create a new file.
2. Save the file with the name "Makefile" (without any file extension).
3. Define the target and its dependencies. For example, if you have a C file named "main.c" that depends on another file named "helper.c", you can write: target: main.c helper.c
4. Specify the commands to build the target. For example, if you want to compile the C files into an executable named "program", you can write: target: main.c helper.c gcc -o program main.c helper.c
5. Save the Makefile.

The resulting Makefile will have a target named "target" that depends on "main.c" and "helper.c". When you run the "make" command, it will check if any of the dependencies have changed and execute the corresponding commands to build the target.

Note: In the makefile example above, the command to build the target uses the "gcc" compiler. You can modify it according to your specific needs.
