稍后再看

#include <iostream>

using namespace std;

int main()

{

int seconds;

cout<<"请输入秒数：";

cin>>seconds;

 

int days = seconds / ( 24 * 60 * 60);

int hours = (seconds - days * (24 *60 *60)) / (60*60)

int minutes = (seconds%(60*60)) / 60;

int secondsLeft = seconds %60;

 

cout<<days<<"天"<<hours<<"小时"<<minutes<<"分钟"<<secondsLeft<<"秒"<<endl;

 

return 0;

}

 

#include <iostream>

using namespace std;

 

int main()

{

int girlsNumber;

int boysNumber;

int total;

cout<<"请输入女生数量：";

cin>>girlsNumber;

cout<<"请输入男生数量：";

cin>>boysNumber;

total=girlsNumber+boysNumber;

int percent = (girlsNumber / float(total))*100;

cout<<percent<<"%" <<endl;

 

return 0;
