C++ 如何报告每个县的获胜者并打印两名候选人的条形图'；总票数？

该程序将统计来自四个县总计和每个县的两名候选人的选票，并显示获胜者。用户必须输入每个县和候选人的姓名和选票。我让程序按照上述目标正确运行。但我想更进一步，显示每个县的获胜者，并打印出每两位候选人总选票的条形图。 要打印条形图，我将使用

PrintGraph

，但不确定如何使用字符串

#include<iostream>
#include<string>
#include<vector>

int tier1(
    const std::string& c0,
    const std::string& c1,
    const std::vector<std::string>& counties);

{
    cout << "Welcome to the VoteTime Program. Please do what it tells you.\n";
    cout << "After you name the two candidates and four counties, make sure the votes doesn't go over 100 votes.\n";

    std::string c0;
    cout << "Please name the candidate 0. (For example: Bob)\n";
    std::getline(cin, c0);

    std::string c1;
    cout << "Please name the candidate 1. (For example: John)\n";
    std::getline(cin, c1);

    std::vector<std::string> counties;

        std::getline(cin, county);
        counties.push_back(county);
    }

    int return_val = tier1(c0, c1, counties);
    if (return_val < 0) // print an error
        return 0;

        {

            exit(1);
        }
    }

    int candidateOneVotes = 0; //resetting 
    int candidateTwoVotes = 0;
    for (i = 0; i < 8; i = i + 2)
    {

        cout << votes[i+1] << "\n";
        candidateOneVotes += votes[i];
        candidateTwoVotes += votes[i+1];
    }

CUT请按照它告诉你的去做。-伙计，你开始是专横的。这都可以学习一个简单的矢量和字符串的C++教程。你哑巴，去完全地学习它。哈哈哈，我不是那个意思。当然，我是这样做的。你认为我是如何打出这个程序的大部分的？我看了几篇教程，觉得有点迷惑。我，因为我显然需要把字符串转换成int。我上个月刚开始C++，给我一个休息时间：
