数组解了

没人想到用循环吗？

#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; }
