Does anyone know if there is an "TextOut" equivalent function for numbers? I need to draw some floating point numbers, or at least integers on screen in the WM_PAINT case. I am able to draw text like so: TextOut(hdc, 695, 125, "Hello", 10); but I need something similar for float or integers.
You sprintf() it to a string, then output the string you've created.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Ok, works for the most part, but there is some garbage at the end of the string. Something like this:

That looks like you are going out of bounds on your char array. You may need to tack on a '\0' char at the end of your data to signal the end of the string.
You have to work pretty hard to make sprintf() omit the \0 at the end of the string.
More likely, it's one of
Code:char buff[2]; // too small sprintf( buff, "%d", myint );Code:char *buff; // not allocated sprintf( buff, "%d", myint );
