Quick Start

Compile

$ make

All the source files in src/ will be compiled and generate binary files to the bin/ in each subdirectory.

Run

Fast compile & run at one time!

Execute this command:

$ make run

At the project root directory, then you can see all the program output on your terminal 🎉

Clean

It's easy to clean all the output files, just enter the following command at the project root directory:

$ make clean

Then you would find out all the output files are gone away!
