这段代码我提交是这样，要是你们提交后不是0ms… 关我啥事？ 给你们判这个的是ACGO的评分系统又不是我"v" ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ 先讲一下Switch怎么用 这样是不是比一堆if好？ ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ AC代码： 如果你不加break…… 就像这样 要是你小子偷懒不加break…… 那就给我门外竖着！！！！！！！！！！！！！ 要是不加，无论你输入什么，它都会输出"MondayTuesdayWednesdayThursdayFridaySaturdaySunday" 把这玩意提交的后果不用我多说…… ACGO的评分系统会WA的一声红温，然后你就哇的一声哭了"v" ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ if(你得到了一堆红WA) { 我只能说 你这么在意这个评分系统干什么啊？ 他会把人的付出给异化掉的 知不知道什么叫异化跟具体化 你能说你能这样讲吗 我给你打个比方 //别看了，没有MVP 你自己发光发热就好管他什么评分不评分 //别误解了，我是叫你坚持改代码直到对为止，不是叫你无视评分系统"v" } ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ ALL IN ALL if的时间约是5ms，switch加cin是1ms，switch加scanf是0ms 因为scanf能拉爆你那185体育生cin All in all,"scanf" is quicker than "cin". （总之，“scanf”比“cin”更快） 都说到这了，那你们就拿出本子吧： 固定搭配：All in all 意为总之，常用于句首表示总结 A is quicker than B 意为“‘A’比‘B’更快” 看我多善良，还顺便教你们英语 所以为什么还不点赞！！！ 至于scanf 和 printf的用法…… 你们要学会借助强大的互联网

Switch if

#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 cout<<"Sunday"; }

#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"; } }

#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 <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"; } }

#include<bits/stdc++.h> 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; }

switch是个好东西

#include <iostream> 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; default:cout<<"Sunday";break; } 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！！！
