给定一个整数N，判断其正负

#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;
    if(n>0){
        cout<<"positive";    
    }else if(n==0){
        cout<<"zero";
    }else if(n<0){
        cout<<"negative";
