im trying to output the players health and mana for my game but according to the error in deccpp
invalid conversion from 'int' to const char*
textout_ex( buffer, font, text, x, y, color, color);
does not work with integers. so how do i print integers to the screen?

#include <sstream>
using namespace std;

...

stringstream ss;
ss << 49;

textout_ex(buffer, font, ss.str().c_str(), x, y, color, color);

Or (because I know someone else is going to post this ):

textprintf_ex(buffer, font, x, y, color, color, "%d", 49);

On a side note: Using the same color for fg and bg is probably not what you want. I'd recommend -1 for your bg parameter.

How is my posting?

I dont really understand the second function you did. I get the first 6 parameters but what are the last two? The int and ....?

Read about the printf function:
printf

Just stick with the first solution, its better anyway.

You should probably read (or re-read) some tutorials on C/C++ basics as well.

I'd go with the second method for consistency.

text_printf is Allegro's version of the standard printf function with extra parameters (destination bitmap, colour, position).
