如何在Mac终端中运行源代码？

Question

Please please help me, I am a computer illiterate female looking to convert a group of (.cng files) into jpegs. I found a source code on a blog that instructs me to

Build it, then run it with something like this:

cng2jpg /path/to/images/199x/1990101/*.cng

Here is a link to the source code

Does anyone know how I can run the source code to convert the files?

Here is a link to the blog post for reference for what exactly I am doing

Answer 1

First, put the source code into a file named cng2jpg.c . Then open a terminal, navigate with cd into the directory where you placed that file and type

cc -o cng2jpg cng2jpg.c

This creates the program cng2jpg . You can execute it by typing

path/to/cng2jpg input_file.cng

where path/to/cng2jpg is the path where cng2jpg was generated in the previous step.
