Here's a little christmas program:
- Code: Select all

#ifdef _WIN32

#else

sstr << "beep -f " << frequency << " -l " << duration;
system(sstr.str().c_str());
}
void Sleep(unsigned int milliseconds)
{
timespec t;
t.tv_sec = milliseconds / 1000;
t.tv_nsec = (milliseconds - t.tv_sec * 1000) * 1000000;
nanosleep(&t, NULL);
}
#endif
using namespace std;

std::ostringstream name;
for(int currentOctave = 0; currentOctave <= 9; currentOctave++)
{
float a_oct = 440.0 * pow(2, currentOctave - 4);
for(int i=0; i<12;i++)
{
name.str("");
name << names[i] << currentOctave;
float freq = a_oct * pow(2, (i-9)/12.0f);
theMap[name.str()] = freq;
//cout << name.str() << "=" << freq << endl;
}
}
theMap["p"] = 0;

Compiles on both Windows (mingw) and Linux g++. On Linux you need the Program "beep" installed.
