How does AST look like?


int printf(const char *format, ...);
int
main() {
        printf("hello world\n");
        return 0;
}

Function(main) type(int) args(void)
    Func_Call type(int)
         Symbol(printf) type(int) ARG
               SYMBOL(_string0="hello...") type(char)
    Return (arg) type (int)
         Constant( 0 ) type (int)
