A454.今天是星期几

#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"; }

解题思路 按照题目给的条件写就行了，很简单 代码 我用的是if语句，但貌似switch好像更快

#include <iostream> using namespace std; int main (){ int a; cin >> a; if(a == 1){ cout << "Monday"; }else if(a == 2){ cout << "Tuesday"; }else if(a == 3){ cout << "Wednesday"; }else if(a == 4){ cout << "Thursday"; }else if(a == 5){ cout << "Friday"; }else if(a == 6){ cout << "Saturday"; }else{ 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 if(n==7){ cout<<"Sunday"; } return 0; }

暴力纯输出，十分简单！！！
