My whole code is far too long to post, so I will just describe the parts around where it doesn't seem to be working... I am declaring and opening an ifstream in int main, and then I am calling a procedure which uses that ifstream. The ifstream is not declared, opened or closed in the procedure. I am calling 5 chars and the ifstream all by reference in the procedure. I am cannot figure out what is wrong. The "no match for opporator <<" is absolutely baffeling to me.

This is my procedure...

I appreciate any help I can get thank you.

Did you include <fstream>?

Look at the last line. You could have easily came up with something much simpler:

#include <fstream>

void drawreplace(char&, char&, char&, char&, char&, std::ifstream&);

int main()
{
   char c;
   std::ifstream dummy;
   drawreplace(c, c, c, c, c, dummy);
}

This compiles fine.

Now given the above, get it to give the same error as you're seeing now. If you can't, then examine the code above to see what it does that is different than what yours does.

Every C++ compiler error can be reproduced with a simple example, there are no exceptions to that rule.
