#include <iostream> using namespace std; int main() { int n; cin>>n; if(n>0) cout<<"positive"; else if(n==0) cout<<"zero"; else cout<<"negative"; return 0; }

#include <iostream> using namespace std; int main(){ int N; cin>>N; if(N>0){ cout<<"positive"; }else if (N==0){ cout<<"zero"; }else if(N<0){ cout<<"negative"; } }

#include<iostream> using namespace std; int main(){ int n; cin>>n; if (n>0)cout<<"positive"; else if (n==0)cout<<"zero"; else cout<<"negative"; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int a; cin>>a; if(a>0){ cout<<"positive"; }else if(a==0){ cout<<"zero"; }else{ cout<<"negative"; } return 0;}

非常简单好吧~~ #include<iostream> using namespace std; int main(){ int N; cin>>N; if(N>0){ cout<<"positive"; } else if(N==0){ cout<<"zero"; } else{ cout<<"negative"; } }

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ 几个if搞定 ----------------------------------------------------------------------------------------------------------------------——————————————————————————————————————————------ #include<cstdio> using namespace std; int main(){ int N; scanf("%d",&N); if(N==0){ printf("zero"); }else if(N>0){ printf("positive"); }else{ printf("negative"); } return 0; }

N=int(input()) if N>0: print('positive') elif N<0: print('negative') elif N==0: print('zero')

N=int(input()) if N > 0: print("positive") elif N == 0: print("zero") elif N < 0: print("negative")

#include<bits/stdc++.h> using namespace std; int main(){ int n; cin>>n; if(n>0){ cout<<"positive"; } else if(n==0){ cout<<"zero"; } else if(n<0){ cout<<"negative"; } }

#include <iostream> using namespace std; int main(){ int N; cin>>N; if(N>0){ cout<<"positive"; } if(N==0){ cout<<"zero"; } if(N<0){ cout<<"negative"; } return 0; }
