嗨，这里的初学者。我的代码的函数count_vote()是错误的，我已经用尽了自己试图找出我做错了什么。我的攻击计划是改变我输入的“vote”字符的大小写，然后将与它的ASCII字符相关联的整数值与候选人的第一个字母相等。如果有匹配，我将递增与该候选人相关联的选票计数变量。
我在将单个字符作为ASCII值阅读时遇到了麻烦，并且当我试图在count_vote() for循环中打印这些值时出现了奇怪的行为;输入的每个字母被解释为具有相同的整数值。
请提供一些建议，我可以如何修复我的janky代码。谢谢！

    {
        printf("%s has won the vote! Praise %s!\n", candidate_3, candidate_3);
    }

}

当试图从我的count_vote的for循环中打印单个字符值时，每个字符输入都被解释为具有相同的整数值。
