Question

I have the following code, but it causes an exception. Without itoa “games” I don’t think there’s a problem. TextOutA is because I use winapi.

char* p1 = new char[2];
itoa(10,p1,10);
TextOutA(hDC,5, currenty,p1,2);
delete[] p1;

Answer 1

Your stringbuffer is too short

itoa overruns the buffer capacity in writing the null termination character.

char* p1 = new char[3];
itoa(10,p1,10);
TextOutA(hDC,5, currenty,p1,2);
delete[] p1;

I suggest you make the buffer big enough to accomodate the full integer range.

Edit Just in case, elaborating on the string stream suggestion:

#include <sstream>

//....
{
    std::stringstream ss;
    ss << 10;
    std::string s = ss.str();
    TextOutA(hDC, 5, currenty, s.c_str(), s.length());
}
