c++ - "else"错误之前的预期主表达式

Question

我得到expected primary-expression before "else"第一个 else 的错误，我不明白为什么。我对所有支撑进行了三次检查。

if(Owin = win)
{
    cout << "The computer has defeated you!\n\n";
    cout << "Would you like to play again? (Y or N) : ";
    cin >> restart;
    if(restart == 'Y' || restart == 'y');
    {
        cout << "\n\n\n";
        main()    ;
    }

    else
    {
        cout << "Good Bye!\n\n";
        system("pause");
        return(0);
    }
}
else
{
}

Answer 1

if(restart == 'Y' || restart == 'y');

删除那里的分号以修复错误。这个 ; 结束了 if 语句，这意味着 else 实际上不是任何 if 语句的一部分，因此错误。
