Hi, I am writing a C++ program that will create some files based on user input, I am using the X.append() function to append the file extension to the input, The only problem is that string will not work with ofstream and it needs to be converted to a char[].
In advance, Thanks for your help!

use the c_str() method to get the character array representation.

CODE
string filename = "myfile.txt";
ofstream ofs( filename.c_str() );

u dont need to use append with strings, the following example will work fine.
CODE

{
string location="test";
location+=".txt";
}

Thanks, Both of those functions work, I just found a another way, the strcat() function :

CODE
cout << strcat("STR", "STR");

or
CODE
ofstream FILE(strcat(userinput, ".ext"), ios::blablabla);

Thanks for your help! biggrin.gif

You were better off the way you had it before - strcat is a 'C' function. You should try to avoid using 'C' code when writing C++ (The two languages don't really mix very well)
