Thread: Problems with int to char...

I'm using the following code to use an int variable (hard coded here but normally cinned by a user) as the beginning of a filename, this code should work, but i think i may be messing up my steps, i get the error: 'can not turn char* to int' when i try to compile, here's the code...anyone know whats wrong??

Code:

int studentID="04390"


template <class T> std::string toString(const T& val) {
	std::ostringstream strWriter;
	strWriter << val;
	return strWriter.str();
}

int main() {

	std::string filename=toString<int>(studentID) + ".xml";
	std::ofstream file (filename.c_str());
	//etc.
return 0;
}

thanks for your help

int studentID="04390"

Simple. You are trying to set StudentID (an int) to the string "04390" (a char *).

You may want to do this instead:

int StudentID = 4390; //(notice, no preceding zero's are included)

or:

char* StudentID = "04390";
