非法的其他没有匹配的if

Question

似乎我的if语句不起作用，而且如果＆＃34;错误信息。任何帮助都会很棒，谢谢。

#include "stdafx.h"
#include "windows.h"
#include "iostream"

using namespace std;

int igame = 0;

int main()
{
    Sleep(1000);
    cout << "welcome to the Wild Casino!";
    Sleep(1000);
    cout << "\nplease select a game to play. 1 for Slots, 2 for Roulette, and 3 for Blackjack: ";
    cin >> igame;

    if (igame == 1);
    {
        cout << "\nWelcome to Slots";

    }
    else if (igame == 2);
    {
        cout << "\nWelcome to Roulette";
    }
    else
    {
        cout << "\nWelcome to Blackjack";
    }


Sleep(1000000);
return 0;

}

Answer 1

if (igame == 1);

最后你有一个额外的分号 - 这相当于

if (igame == 1) { }

您的代码会创建一个格式错误的程序：

if (igame == 1) { }

{ // block not attached to if
    cout << "\nWelcome to Slots";
}
else if (igame == 2) { } // this else has no matching if
{
    cout << "\nWelcome to Roulette";
}
else // this else has no matching if
{
    cout << "\nWelcome to Blackjack";
}
