#include<iostream> using namespace std; int main(){ }

#include<bits/stdc++.h> using namespace std; int sum; int main(){ int a; cin>>a; if(a%70){ cout<<"monday"; } if(a%71){ cout<<"tuesday"; } if(a%72){ cout<<"wednesday"; } if(a%73){ cout<<"thursday"; } if(a%74){ cout<<"friday"; } if(a%75){ cout<<"saturday"; } if(a%7==6){ cout<<"sunday"; } return 0; }

代码：

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

像这种题我们可以用switch来做，这用会更简洁

上代码，（懒得说了）。 今日图片：

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

#include <iostream> using namespace std; int main(){ int n; cin >> n; n+=1; n=n%7; switch(n){ case 1: cout << "monday" ; break; case 2: cout << "tuesday" ; break; case 3: cout << "wednesday" ; break; case 4: cout << "thursday" ; break; case 5: cout << "friday" ; break; case 6: cout << "saturday" ; break; case 0: cout << "sunday" ; break; } return 0; }

#include<iostream> using namespace std; int n; int main(){ cin>>n; if(n%71)cout<<"tuesday"; else if(n%72)cout<<"wednesday"; else if(n%73)cout<<"thursday"; else if(n%74)cout<<"friday"; else if(n%75)cout<<"saturday"; else if(n%76)cout<<"sunday"; else cout<<"monday"; return 0; }

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

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

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