不会真有人不用列表吧，一个一个列出来的： if(a%7==0) { cout<<"monday"; } 这种

谁能告诉我为啥不能用switch

#include<iostream> using namespace std; int main(){ return 0; }

#include <bits/stdc++.h> using namespace std; int main(){ int a;cin>>a;int b=a%7; if(b6) cout<<"sunday"; if(b5) cout<<"saturday"; if(b4) cout<<"friday"; if(b3) cout<<"thursday"; if(b2) cout<<"wednesday"; if(b1) cout<<"tuesday"; if(b==0) cout<<"monday"; return 0; }
