error in program help ASAP pleeease
I am getting a segmentation error in this file, I think it has something to do with the row, rows, col, cols part....Tearing my hair out here...Can anyone help, its due this afternoon. Counts chars in a file.
#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>
const int rows = 26;
const int cols = 51;
static ifstream infile;
//Open file
void Openfile(void)
{
const int fileSIZE=100;
char filename[fileSIZE];
cout << "Enter data file name:" << endl;
cin.getline(filename, ios::in | ios::nocreate);
if(!infile.good())
{
cout << "Error:unable to open" << filename << endl;
exit(1);
}
}
