My Code:
#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
int Auswahl;
int Zeit;
do
{
cout << "1 für Sekunden" << endl;
cout << "2 für Minuten" << endl;
cout << "3 Hilfe" << endl;
cout << "4 um zu Beenden" << endl;
cin >> Auswahl;
cout << endl;
switch (Auswahl)
{
case (1):
{
cout << "Gib die Zeit in Sekunden ein: ";
cin >> Zeit;
for (Zeit; Zeit > 1; Zeit--)
{
cout << "Noch " << Zeit << " Sekunden" << endl;
Sleep (1000);
}
if (Zeit == 1)
cout << "Noch " << Zeit << " Sekunde" << endl;
PlaySound (L"C:\\WINDOWS\\Media\\notify.wav", NULL, SND_SYNC);
cout << "Zeit ist abgelaufen" << endl << endl;
} break;
case (2):

cout << "Gib die Zeit in Minuten ein: ";

}
I Use on Windows Code::Blocks RC2 with the newest nightly build. My Compiler ist MinGW Version 5.1.3. I used a console aplication.

PlaySound (L"C:\\WINDOWS\\Media\\notify.wav", NULL, SND_SYNC);
Hi,
remove "L" from all strings in PlaySound (...) calls.
P.S. Also I think that code
for (Zeit; Zeit > 1; Zeit--)
{
}
for (int counter = Zeit; counter > 1; counter--)
{
cout << counter;
}

Do you know what's wrong here?
I removed the L and I changend the fors to
for (int i = Zeit; i > 1; i--)
Is it standard to initialize the variables in the loops?
