必对题解（含：if、switch、数组）

代码如下（if语句）：

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

也可以这样写（switch语句）：

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

代码如下（数组）：
