Convert integer/long to a string???

[Warmaster199]

I have made a function for displaying text basing the coordinates on a given XY point:

void xytext(int x, int y, char *text)
{
    move_to(x,y); /*move graphics device to x,y */
    plots(text);     /*plots the text string */
}

This will plot the given text to a given point. This is intended for powerc(you can use another compiler) or any compiler that doesn't have the function outtextxy();

Here is my problem: I would like to turn an integer so I can put it into a string, to display it using this function. I'm not good with strings, so can you tell me how I could add that string(converted int) to the end of another string(a phrase), so I can do something like this:

"Mouse X = " + (Interger(say 77) to string)
"Mouse X = " + "77"
"Mouse X = 77"

You get it? Please help me on this. It's EXTREMELY IMPORTANT!!!
