完整代码在此 好像运行时间是 5ms 哈哈哈

#include <iostream> using namespace std; int main(){ int a; cin >> a; if(a1){ cout << "Monday"; } if(a2){ cout << "Tuesday"; } if(a3){ cout << "Wednesday"; } if(a4){ cout << "Thursday"; } if(a5){ cout << "Friday"; } if(a6){ cout << "Saturday"; } if(a==7){ cout << "Sunday"; } return 0; }

#include <bits/stdc++.h> using namespace std; int main(){ int a; cin >> a; if(a1){ cout << "Monday"; } if(a2){ cout << "Tuesday"; } if(a3){ cout << "Wednesday"; } if(a4){ cout << "Thursday"; } if(a5){ cout << "Friday"; } if(a6){ cout << "Saturday"; } if(a==7){ cout << "Sunday"; } return 0; }

#include<iostream> #define ikun int using namespace std; int main(){ ikun a;//别问我为啥能对 cin>>a; switch(a){ 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 7:cout<<"Sunday";break; } return 0; }

看这里还没有大佬发map的代码，赶紧水一波发一个 首先介绍一下map： map是一个由键（key）和值（value）组成的储存空间 每一个key都对应一个value。 命名方式： map<类型,类型> map名称 使用方法就更简单，赋值可以直接map[内容]=内容 注意，map不能直接输入，但可以直接查找并输出，如： cout<<mp[内容]； 到这里就简单的介绍完了，上代码： map代码会比普通分支代码量少，可以用来偷懒练习 大家可以学起来了~~

#include <bits/stdc++.h> using namespace std; string s[8]={"","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"}; int main() { int n; cin>>n; cout<<s[n]; return 0; }

代码如下：

#include<iostream> using namespace std; int main(){ int a; cin>>a; if(a1) { cout<<"Monday"; } if(a2) { cout<<"Tuesday"; } if(a3) { cout<<"Wednesday"; } if(a4) { cout<<"Thursday"; } if(a5) { cout<<"Friday"; } if(a6) { cout<<"Saturday"; } if(a==7) { cout<<"Sunday"; } return 0; }

万能头真的是——泰裤辣！ 有了万能头，就再也不用担心少写头文件了

#include <iostream> using namespace std; int main(){ int a; cin>>a; if(a1) cout<<"Monday"<<endl; if(a2) cout<<"Tuesday"<<endl; if(a3) cout<<"Wednesday"<<endl; if(a4) cout<<"Thursday"<<endl; if(a5) cout<<"Friday"<<endl; if(a6) cout<<"Saturday"<<endl; if(a==7) cout<<"Sunday"<<endl; return 0; }

#include<iostream> using namespace std; int main(){ string a[7]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"}; int b; cin>>b; cout<<a[b-1]; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int n; cin>>n; if(n0){ return 0; } 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(n7){ cout<<"Sunday"; } return 0; }

##前言## 太简单了，懒得喷。 ##代码部分## ##总结部分## 还是那三个字：好简单！

#include<iostream> using namespace std; int main(){ int a; cin>>a; 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==7){ cout<<"Sunday"; } return 0; }

#include <iostream> using namespace std; int main(){ int n; cin>>n; 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{ cout << "Sunday"; } return 0; }

内有详解 #include <iostream>; using namespace std; int main(){ int a; cin>>a;输入星期 switch(a){//swictch函数 case 1:cout<<"Monday";break;//判断星期并输出英文 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 7:cout<<"Sunday";break; }//完成了 return 0; }
