my code is as follows

//creates a 10 by 10 word search puzzle
//words determined by a specified filed
//word locations then specified by user
//program creates random letters to fill in the puzzle
//programmer : Tyler Sievers
#include <iostream>
#include <fstream>

const int k=5;    // 5 is the most words allowed in file. constant for the first array
const int r=10;		//10 rows high
const int c=10;		//10 collomns wide

void getfile(ifstream&);
void populatearray(ifstream&, string[]);
void testfcn1(string[]);  //comment when done!!!!	
void displaygrid(char[][c]);
void colomncounter();
void horizontalborders();
void fillgrid(char[][c]);
void printgrid(const char[][c]);

void main(){
	//more or less does nothing :]

last night when i called it quits none of these errors came up and i can't see what could be causing them any ideas?

Your printgrid() and displaygrid() function prototypes are swapped. One takes a const char[][], and the other takes a normal char[][]. The prototypes have it the opposite way.

I thought i had fixed that last night before i went to sleep... well crap... you have been an incredible help zhuge thanks a lot man
