itoa

I'm trying to use itoa method but it won't work here, on c++11.
there is a another way to convert int to const char?

Use a stringstream.

#include <iostream>
#include <sstream>
#include <cstring>

int main()
{
    char buf[40];

    int m = 456;
    std::ostringstream ss;
    ss << m;
    strcpy(buf, ss.str().c_str());

    std::cout << "buf = " << buf << std::endl;
}

i'm using this on a infinite loop to render a variable on the screen, how can i clear the buffer? and ss?

If you declare the stringstream locally inside the loop, it will always start out empty - unless you use it for several different ints within that loop. Or clear it like this:

#include <iostream>
#include <sstream>

int main()
{
    int n=123, m = 456;
    
    std::ostringstream ss;  
    ss << m;
    std::cout << ss.str() << std::endl;
    
    ss.str(""); // clear the stringstream
    ss << n;
    std::cout << ss.str() << std::endl;    
}

You don't need to clear the buffer - indeed you may not need it at all, it depends on what it is you are trying to so.

it is working, is rendering the enemy hp value on the screen
thanks.
