!printf main tests.md

Usage

Use gcc {your files} main.c -D MINE to compile main.c with your program

Use gcc main.c to compile main.c with libc's implementation

Tests are easy to add, and the TEST macro will display what printf (or ft_printf) returns

Use -D BONUS to test the bonuses

Commands gcc *.c -D MINE && ./a.out > got.txt, gcc main.c ./a.out && ./a.out > expected.txt, diff got.txt expected.txt might be useful
