循环在无效战斗场景中不运行。

Question

我是C++的新手，在一项任务上遇到了一些困难。到目前为止，我的计划如下：

#include "stdafx.h"

#include <iostream>
#include <string>
using namespace std;

void fight(string heroName, int arrowCount, int enemyCount);
int main(int argc, char** argv) {

    string heroName = "Legolas";
    int arrowCount = 3;
    int enemyCount = 3;

    cout << "Welcome to the Arena, the battle will begin shortly." << endl;
    system("pause");
    cout << "\nToday's competitors: " << "\n" << heroName << "\n" << "3 Orcs" << endl;

    system("pause");

    cout << "\n" << heroName << " will be given 3 arrows" << "\n" << "3 Orcs will be given daggers. \n";

    system("pause");

    cout << "\nThe battle begins in...\n 3...\n  2...\n   1..." << endl;

    system("pause");

    fight(heroName, arrowCount, enemyCount);
}

void fight(string heroName, int arrowCount, int enemyCount) {

    for (int x = arrowCount; x <= 0; x--) {

        if (arrowCount == 3) {
            cout << "\n" << heroName << " fires arrow at Azog." << "\nAzog has fallen due to lobotomy by arrow." << "\nLegolas notices he has 2 arrows remaining." << endl;
            system("pause");
        }

        if (arrowCount == 2) {
            cout << "\n" << heroName << " fires arrow at Dular." << "\nDular has taken an arrow to the knee and is now longer an adventurer." << "\nLegolas notices he has 1 arrow remaining." << endl;
            system("pause");
        }

        if (arrowCount == 1) {
            cout << "\n" << heroName << " fires arrow at Nagrub." << "\nNagrub has lost his testicles." << "\nLegolas notices he is out of Arrows." << endl;
            system("pause");
        }
    }
}

我遇到的问题是，for循环似乎没有初始化。一切运行良好，直到程序的“无效战斗”部分。我该怎么纠正呢？

Answer 1

你是说for (int x = arrowCount; x >= 0; x--) {吗？注意，for循环条件检查是在运行循环体之前计算的。

目前，如果x是正的，则循环将终止，从变量名判断，情况很可能是这样。

还请注意，for循环的主体既不依赖于x，也不依赖于enemyCount，这似乎很奇怪。
