Thread: Probably simple question: Displaying int's

I'm using DrawText to write some text to my screen. I need to also show some integers, but that function only takes in Strings.

So I guess my question is either one of the two:
1) how do I convert an int to a string?
or
2) is there some better function to use to show text in windows? A function that can also show ints...

Thank you!

You'll need to convert the integer into a string. Here is a quick example. The function you need is sprintf

Code:

char buffer[256] = { 0 };
int nNumber = 123;

sprintf( buffer, "The number is %d", nNumber );

Then you will use TextOut or DrawText to display buffer and it will display "The number is 123". Hope this helps.

int i;
char a[10];

TextOut(hdc, x, y, a, wsprintf(a, "%d", i));

this thread will help you A LOT!

someone told me you shouldn't use itoa, can someone explain to me why?

I used a bunch in a text-based game I made, and never had a problem. I was just wondering, since we are kinda on the topic.

For the record -- use wsprintf if programming for Windows, which I assume you are if you're having problems printing ints.

Using wsprintf and TextOut correctly looks like this:

Code:

int score = 0;
char chScore[] = "Score: %d";
char scoreString[20];

wsprintf(scoreString, chScore, score);

TextOut(hdc, x, y, scoreString, strlen(scoreString));
