禁止抄袭

#include <bits/stdc++.h> using namespace std; int main (){ int a; cin >> a; if (a % 7 == 0 )cout << "monday"; else if(a % 7 == 1)cout << "tuesday"; else if(a % 7 ==2)cout << "wednesday"; else if(a % 7 == 3)cout << "thursday"; else if(a % 7 == 4)cout << "friday"; else if(a % 7 == 5)cout << "saturday"; else if(a % 7 == 6)cout << "sunday"; return 0; }

通过char数组存星期英文，再通过if语句进行判断，是程序达到题目要求

#include<bits/stdc++.h> using namespace std; int main(){ string lst[7]={"monday","tuesday","wednesday","thursday","friday","saturday","sunday"}; int n; cin>>n; if((n+1)%7==0)cout<<lst[6]; else cout<<lst[(n+1)%7-1]; }

#include<iostream> using namespace std; int main(){ int n; cin>>n; n=(n+1)%7; if(n1){ cout<<"monday"; } else if(n2){ cout<<"tuesday"; } else if(n3){ cout<<"wednesday"; } else if(n4){ cout<<"thursday"; } else if(n5){ cout<<"friday"; } else if(n6){ cout<< "saturday"; } else if(n==0){ cout<< "sunday"; } return 0; }

#include <iostream> using namespace std; int main(){ int a; cin>>a; a=(a+1)%7; if(a1){ cout<<"monday"<<endl; }else if(a2){ cout<<"tuesday"<<endl; }else if(a3){ cout<<"wednesday"<<endl; }else if(a4){ cout<<"thursday"<<endl; }else if(a5){ cout<<"friday"<<endl; }else if(a6){ cout<<"saturday"<<endl; }else{ cout<<"sunday"<<endl; } return 0;
