Converting from Int to String

[crrrazydan]

I am making a game with OpenGL, and I have a function that prints the fps (frames per second) on the screen. But the problem is that that function only takes strings in the char *str form, and my fps value is an Int. I am a beginner to C++ (not to 3D though , I'm used to VB), so please explain any suggestions you give a little. Here is my code:


char *str;
int fps;

GetFps(fps);
//Something to convert int to *str here
PrintString(listBase, str);


And for future reference, how do I combine two strings in C++? Like str = str + str2

Thanks! -Dan K

1 question: try with printf family

GetFps(fps);
printf(str,"%d",fps);
PrintString(listBase, str);

don't forget to allocate memor for str.


2 question : if u mean String the class string then u can
use str.append(str2); or str += str2;

This example uses the fancy stringstream class in C++

#include <iostream>
#include <sstream>
#include <string>

using namespace std;

string myString = convertToString(123);

std::string convertToString(int x)
{
std:stringstream o;
if (o << x)
return o.str();
// some sort of error handling goes here...
return &quot;conversion error&quot;;
}
