Hi I'm writing a Program in C++, I believe the program is well written because the program was without error or warning. My problem is the program will not execute. I don't why it will not and don't know what to do. Please help me out.

Humm... This will fail on a program as simple as:
#include <iostream>
use namespace std;
int main(int argc, char *argv[])
{
cout << "http://www.google.com/" << endl;
return 0;
}

hi
why you declare:
char =ch;
and then
ch=fgetc(fp);
I dont understand because fgetc(fp)'s return type is integer, but ch is char.

Try this code itself as the input file. It removes slashes at lines 18,21 etc,... A small error there.
