testing sample:(path->test/homework_t.c)

a = 3;
b = 5;
if (a > b){
    t = a;
}
else{
   t = b;
}

testing method:

1. After u done programming, type "make" in terminal to compile multiple ".c" files at the same time. This is what ya ganna get-> gcc -std=c99 -O0 lexer.c compiler.c main.c -o compiler
2. Type "./compiler test/homework_t.c -ir -run" to demo ur code.

Result:
