unknown errors (to me at least)

I am a relative newcomer to C++. I have some history in BASIC ( I like goto loops!), but the C++ syntax is new to me.

The program I am trying to create is a simple game modifier that changes a value in the game's user.ini file so that a new action will be bound to a certain key.
What I want it to do is open and run through the user.ini file, copying every line exactly until it finds the line that begins with "X=" (with X being the letter the user picked.) where I want to make it "X=playvehiclehorn 1" then continue on copying the rest of the lines of the program and stop when it reaches the end. I don't want the program to overwrite the file it reads from, just to make a copy in the same directory as the program is run, so the user can manually add it.

I am using Bloodshed Dev C++. The compiler is throwing some errors at me I have never seen before. It is giving me errors on lines that don't have any code and past the end of the program. I have used all these commands before, maybe not in the same program, so I should be able to make it work. But no one can honestly say the error messages in Bloodshed help a novice very much . Thanks in advance!

here is my code:

Code:

#include <iostream>
#include <cstdlib>
#include <string>
#include <fstream>
using namespace std;

int main()
{
	char peeker = 'z', def = 'y', newkey = 'H', custkey = 'z', gettest = 'z', peeker2 = 'z', done = 'n';
	string filename, linein;
	ifstream infile;
	ofstream outfile;

	while (def != 'y' || def != 'n')
	{
		cout << "Is your program installed in the default directory?" << endl << "c:\UT2004  (y/n): ";
		cin >> def;
	}

	if (def == 'n')
	{
		cout << "Enter the location of your user.ini file" << endl << "Example: c:\ut2004\system\user.ini" << endl << ": ";
		cin.ignore(400, '\n');
		getline(cin, filename);
		infile.open(filename.c_str() );
	}

*29*	else 
		infile.open("c:\ut2004\system\user.ini");

	if (!infile)
	{
		system("pause");
		return 1;
	}

	outfile.open("user.ini");

	cout << "Do you want to use the 'H' key? (y/n): ";

	while (custkey != 'y' || custkey != 'n')
		cin >> custkey;

	if (custkey == 'n')
	{
		cout << "Enter your new key to bind to the horn. It must be a CAPITAL letter." << endl << "Ex: H  : ";
		cin >> newkey;

	while (newkey < 'A' || newkey > 'Z')
	{
		cout << " Invalid key, enter another: ";
		cin >> newkey;
	}

	while (!infile.eof())
	{
		peeker = infile.peek();
		
		if (peeker == newkey && done == 'n')
		{
			infile.get(gettest);
			peeker2 = infile.peek();

			if (peeker2 == '=')
			{
				outfile << newkey << "=" << "playvehiclehorn 1" << endl;
				done = 'y';
				infile.ignore(100, '\n');
			}
			else
			{
				infile.putback(gettest);
				getline(infile, linein);
				outfile << linein << endl;
			}
		}

		else
*79*		{
			getline(infile, linein);
			outfile << linein << endl;
		}
	}

	infile.close();
	outfile.close();

	system("pause");
	return 0;
*90*  }

lines with errors are marked with: *linenumber*

here are my error messages
Line | Error

Remember backslash in a string is the escape character.

> cout << "Is your program installed in the default directory?" << endl << "c:\UT2004 (y/n): ";
cout << "Is your program installed in the default directory?" << endl << "c:\\UT2004 (y/n): ";

> cout << "Enter the location of your user.ini file" << endl << "Example: c:\ut2004\system\user.ini" << endl << ": ";
cout << "Enter the location of your user.ini file" << endl << "Example: c:\\ut2004\\system\\user.ini" << endl << ": ";

thanks so much! I remember that now, but for the life of me I didn't think of that before! I would have never figured that out. Between that and a stupid missing bracket, the program is at least compiling now. Thanks again!

Glad you got it compiled! Just to correct myself, I probably should have said:
Backslash in a string is the start of an escape sequence. So two backslashes will give you one.

ya, I think I remember now, kinda like you use a backslash to put a quotation mark or a newline character. It is so easy once you remember once . Thanks again, I got it working right!
