Bugs:
* defining multi-line functions from interactive mode
* defining functions with no parameters (in interactive mode?)
* int fact(int i) {
if (i < 2) {
@ -10,12 +9,12 @@ Bugs:
return (i * fact(i - 1));
}
* something wrong with interactive mode after error handling - not clearing token buffer correctly?
* parsing of statements not quite right - seems to optionally want extra tokens at end
Implement:
* operator precedence
* pointer arithmetic
* casts
* fix #include
* char access/char array access/char * access
Improvements:
