C++:需要一个声明

Question

我是一个彻头彻尾的编程菜鸟，我遇到了多个错误，上面写着“需要一个声明”分配给我们的项目需要创建一个文本基础游戏，其中包含攻击对手的角色。我们要制作角色，当我们告诉他们攻击时，我们必须输入正确的 key 进行攻击。

这是我目前所拥有的:

#include <cstdlib>
#include <Windows.h> 
#include <iostream>
#include <string>

using namespace std;

int Opponent;
int showOpponentHealth(int OpponentHealth, int Attack);
int showHealth(int Health, int OpponentAttack);
int showMagic(int Magic);
{ //Error: expected a declaration
public:
    Opponent() : OpponentAttack(0), OpponentHealth(3);
    {
        OpponentAttack = rand() % 100;
        OpponentHealth = rand() % 6 + 10;
    }
}
int getAttack(Opponent);
{ //Error: expected a declaration
    AttRoll = Rand() % 100
    if (AttRoll < getAtt)
        hit
    {
        AttType = 1 - 3
        if (AttType == 1)
            return 30
        else if (AttType == 2)
        return 50
        else if (AttType == 3)
        return 70
    }

    float character::getHeal()
    {
        magicCost = magic - 6;
        Heal = rand() % 3 + 5;
        cout << "Heal value= " << heal << ".\n";
        return Heal;
    }
}
void Battle()
{
    int Health = rand() % 6 + 10;
    int OpponentHealth = rand() % 6 + 10;
    int hit;
}
long timeTest()
{
    //seed the random number generator
    srand(GetTickCount64());
    //rand will give a number between 0 and max integer value
    int waitTime = rand() % 5 + 1;
    for (int i = waitTime; i>0; i--)
    {
        cout << "*";
        Sleep(1000); //wait for 1 second
    }
    char typeThis = rand() % 26 + 97;
    cout << typeThis << ":";
    char playerResponse;

    //this is the window function I'm using to get the time: ULONGLONG WINAPI GetTickCount64(void);
    ULONGLONG startTime = GetTickCount64();

    cin >> playerResponse;

    ULONGLONG endTime = GetTickCount64();

    if (playerResponse != typeThis)
        return -1;
    long deltaTime = endTime - startTime;

    return deltaTime;
}
do  //syntax error
{  //Error: expected a declaration
    cout << " Attack Opponent? \n Yes = 1\n"
        cin >> Attack Opponent;
    if (AttackOpponent == 1)
    {
        OpponentHealth = showOpponentHealth(OpponentHealth, Attack);
        Health = showHealth(health, OpponentAttack);
        cout << "You attacked the Opponent with a light attack.";
        cout << "The Opponent now has " << OpponentHealth << "health left.";
        if (OpponentHealth <= 0)
        {
            cout << "You Win!";
        }
        else if (OpponentHealth > 0)
        {
            cout << "Opponent attacks back";
            cout << "You have" << Health << "health left,";
        }

        else if (AttackOpponent == 2)
            cout << "You attacked the Opponent with a medium attack.";
        cout << "The Opponent now has " << OpponentHealth << "health left.";

        }
    }  //Error: expected a declaration
    int showOpponentHealth(int OpponentHealth, int Attack)
    {
        OpponentHealth = OpponentHealth - Attack;
        return OpponentHealth;
    }

        Health = Health - OpponentAttack;
        return Health;
    }
}
int main()

    cout << "Try the timeTest: " << timeTest() << endl;

    int Health = rand() % 6 + 10;
    if (Health <= 0)
        cout << "You Died. Game Over." << endl;

    int Magic = 10
    else (Magic <= 0)
        cout << "No more Magic." << endl;

    system("Pause");
    return0;
}

错误在括号和“do”处弹出

Answer 1

您的 do{ ... } 循环在任何函数之外。它必须在一个函数内——编译器告诉你它需要一个像这样的函数声明:

long timeTest()

您是说 do-loop 是在 timeTest() 内部吗？
