将整数数组转化成string

#include <iostream>#include <string>using namespace std;const int size = 24;int main(){int i, a[size];    string s;for(i = 0; i < size; i++)a[i] = i;for(i = 0; i < size; i++){char ch[5];itoa(a[i], ch, 10);string tmp(ch);s += tmp;s += ",";//加上这句则在每两个整数之间用逗号隔开。}cout << s << endl; // 输出为：0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,return 0;}
