#include<iostream> #include<cstdio> using namespace std; int main(){ int n,a,b; cin >> n; a=n/2; if (n%2==1){ b=a+1; cout <<b; }else { cout << a; } }

#include<bits/stdc++.h> using namespace std; int main() { int n; cin>>n; if(n%2!=0)cout<<n/2+1; if(n%2==0)cout<<n/2; return 0; }

n = int(input()) a = n/2 ans = int(a) if a == ans: print(ans) else: s = int(a) x = s+1 print(x)

很简单

遇到~~~~~~（红色的）不要慌，直接提焦（不信自己运行A个C）

#include <iostream> using namespace std; int main(){ int n; cin>>n; if(n%2==1){ cout<<n/2+1; }else{ cout<<n/2; } return 0; }
