Question

In this code:

this->_label = CCLabelTTF::labelWithString(number,"Artial", 32);

number is 5, but must be a const char *.

How can I convert number from an int to the required const char *?

Answer 1

The only three-argument call listed here is:

+ (id) labelWithString:  (NSString *)  string
       fontName:         (NSString *)  name
       fontSize:         (CGFloat)     size

That means number should not be an int but should indeed be a const char *.

If you want to populate it with the string "5" instead of the integer 5, you’ll need to convert it to a string first.

Depending on the language you’re using, this could be something like:

char buffer[20];
sprintf (buffer, "%d", number);

(for C) or using something like stringstreams in C++.
