头文件string.h和string是有区别滴~

#include<iostream>#include <string>using namespace std;int main(){while(1){int num;string arr[1000];string result;cin>>num;if(num==0)break;int max=0;int i=0,j=0,sum=0;for(;i<num;i++){cin>>arr[i];sum=0;if(i==0)result=arr[i];for(j=0;j<i;j++){if(arr[i].compare(arr[j])==0){sum++;if(sum>max){max=sum;result=arr[i];}}}}    cout<<result<<endl;}return 0;}
