C++ 字符串不会正确输出值

Question

该程序的目标是创建一个函数 (combineStr)，该函数将字符串连接多次。

#include <iostream>
using namespace std;

string combineStr(string input, int times) {
    string output = "";
    for(int i = 0; i < times; i++){
        output += times;
    }
    return output;
}

int main(){
    string input;
    int times;
    cout << "Enter a string: ";
    cin >> input;

    cout << "Enter a number of times: ";
    cin >> times;
    if(times == 0){
        return 0;
    }

    string output = combineStr(input,times);

    cout << "The resulting string is: " << output << endl;
}

出于某种原因，当我编译和运行程序时，它只是输出“结果字符串是:”而没有重复的字符串。帮忙？

修改循环内的语句。

output += times; to output += input;

string combineStr(string input, int times) {
    string output = "";
    for(int i = 0; i < times; i++){
       output += input;
    }
}
