C++ to C

[T'Scoopz]

Hello, I just need help converting this baby in plain old vanilla C.

You can tell me the equivalents of C to C++ or whatever is more convenient for you.

I'm compiling in MS Visual Studio C++ 2008 and it gives me mostly "undeclared identifiers" and "syntax errors".

Thanks in advance!

#include <iostream>
#include <ctime>

enum EMove {	keUp = 'w',
			keDown = 'z',
			keLeft = 'a',
			keRight = 's'};

void PrintBoard(char[4][4]);
void LocateSpace(int&, int&, char [4][4]);
void Randomize(char[4][4]);
void Move(char[4][4], const EMove);

int main() {
	char caaBoard[4][4];

printf()....

Oh and include stdio.h instead of iostream. And time.h instead of ctime.

Also, C doesn't have references, so you'll have to convert those reference parameters to pointers.
Just out of curiosity, why do you want to convert it to C?

See here.

Thanks again.

And I answered your question on the other forum.
