C++ 中int 数组转换为string

#include<iostream>#include<string>#include<sstream>using namespace std;string IntToString(int &);int main(){int a[]={1,2,3,4,5,6,7,8,9,10};int arrayLength=sizeof(a)/sizeof(a[0]);string strs;for(int i=0;i<arrayLength;i++){int &temp=a[i];strs+=IntToString(temp);}cout<<strs<<endl;return 0;}string IntToString(int & i){  string s;  stringstream ss(s);  ss<<i;  return ss.str();}
