如何通过C++编写一个简单的倒计时程序?
#include
#include
#include
#include
using namespace std;
int main() {
int hours, minutes, seconds, totalSeconds;
cout << "Enter hours: ";
cin >> hours;
cout << "Enter minutes: ";
cin >> minutes;
cout << "Enter seconds: ";
cin >> seconds;
totalSeconds = hours * 3600 + minutes * 60 + seconds;
for (int i = totalSeconds; i >= 0; i--) {
int h, m, s;
h = i / 3600;
m = (i % 3600) / 60;
s = i % 60;
cout << h << ":" << m << ":" << s << endl;
Sleep(1000);
system("cls");
}
cout << "Time is up!" << endl;
return 0;
