Re: [Dev-C++] What lib should i be using instead?

I am not all to familiar with the string class that you are using, but
"filename += number" may not do what you think.

try this instead:

//
string filename = "help";
int number = 0;
filename += itoa(number); // convert int to char before appending it to
string.
cout << "{"  << filename << "}" << endl;
//

You will now see that a space is added between filename and number. This
character position is to represent a minus sign if number is negative. Your
string class will probably have a function to get rid of this character.
