String Addition Problem...
I'm trying to add two variables (both strings) in Dev-C++, and it tells me that there's no matching operator+. Every tutorial and example I've found on the net says that the syntax I'm using is just fine, so I don't understand why I'm getting this error. If anyone could help, that would be great. Thanks in advance. Here's the code, rather short. The declarations have values other than NULL, but I didn't think it was particularly important.
Code:
//DECLARED AT THE GLOBAL SCOPE
string MOD_DIR = NULL;
//DECLARE AT THE FUNCTIONAL SCOPE
string filename = NULL;
int config_Type
switch(config_Type)
{
case 1:
filename = MOD_DIR + filename + ".ini";
break;
}
