c++ - 需要帮助从不同的功能输出东西(C++)

Question

我对 C++ 和一般编码还很陌生。我正在尝试制作一个基本的小的多项选择类型的练习游戏，但我遇到了一个难题。

程序也没有输出我想要的。这是代码:

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>

using namespace std;

void sword(int damage);
void fists(int damage);

static int enemyHealth = 250;

int main() {
    srand(time(0));

    string SOF; //Abreveation for "Sword Or Fists"

    cout << "You will be fighting a mean bad guy. Are you using a sword, or your fists?\n";

    while (SOF != "sword" && SOF != "fists"){
        cout << "Please enter your choice of either 'sword' or 'fists': ";
        cin >> SOF;
    }

    cout << "Okay! Time to fight! \n";

    if (SOF == "fists") {
        void fists();
    }
    else if (SOF == "sword") {
        void sword();
    }
    else{ (NULL); }

    cout << "Congratulations! You have vanquished that foul beast!\n";

    system("pause");
}

//This is for when the user chooses 'sword'
void sword(int damage = rand() % 100 + 50) {
    while (enemyHealth > 0){
        cout << "You deal " << damage << " damage with your sharp sword. \n";
        enemyHealth -= damage;
    }
}

//This is for when the user chooses 'fists'
void fists(int damage = rand() % 10 + 4) {
    while (enemyHealth > 0){
        cout << "You deal " << damage << " damage with your womanly fists. \n";
        enemyHealth -= damage;
    }
}

第一部分工作正常，但是当我输入我选择的 “fists” 或 “sword” 时，输出是:

Okay! Time to fight!
Congratulations! You have vanquished that foul beast!

但我希望它输出用拳头或剑造成的伤害。

如果我能得到一些帮助，那就太棒了。谢谢!

Answer 1

void fists();是声明，不是调用，改为fists();和sword();

其他要看的东西:

• 默认参数在 main 之前的函数声明中声明(或者只是将整个函数移到那里)
• C++ 中的默认参数只计算一次，因此您的代码中的所有“命中”都是相同的
• 局部变量名通常不以大写形式命名，SOF 看起来像是一个#defined 常量或类似的。
