在C++； 我是C++新手，现在通过代码： 所以，我想问，当用户在代码中输入No时，如何重复相同的代码： if (first == "No" ) { cout << "\nPlease Re-enter Your Name. \n"; cin >> name; cout << "\nPlease Re-enter Your Age. \n"; cin >> age; cout << "\nPlease Re-select Your Class. \n"; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Classes" << setw(1) << "|" << setw(15) << left << "Advanced" << setw(1) << "|" << setw(5) << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Mage" << setw(1) << "|" << setw(15) << left << "Sorceress" << setw(1) << "|" << setw(5) << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Fighter" << setw(1) << "|" << setw(15) << left << "Warrior" << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Ninja" << setw(1) << "|" << setw(15) << left << "Assassin" << setw(1) << "|" << setw(5) << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << "\n"; cin >> str_class; if (str_class == "Mage" ) { cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Name" << setw(1) << "|" << setw(15) << left << "Class" << setw(1) << "|" << setw(15) << "Age" << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << name << setw(1) << "|" << setw(15) << left << str_class << setw(1) << "|" << setw(15) << age << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; } if (str_class == "Fighter") { cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Name" << setw(1) << "|" << setw(15) << left << "Class" << setw(1) << "|" << setw(15) << "Age" << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << name << setw(1) << "|" << setw(15) << left << str_class << setw(1) << "|" << setw(15) << age << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; } if (str_class == "Ninja") { cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << "Name" << setw(1) << "|" << setw(15) << left << "Class" << setw(1) << "|" << setw(15) << "Age" << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; cout << setfill(' ') << setw(1) << "|" << setw(15) << left << name << setw(1) << "|" << setw(15) << left << str_class << setw(1) << "|" << setw(15) << age << setw(1) << "|" << endl; cout << setfill('-') << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << setw(15) << "-" << setw(1) << "+" << endl; } cout << "Your Profile Has Been Changed. \nDo You Want This Profile To Be Sent To The Academy Database ? (Yes/No) \n"; cin >> first; } if（first==“No”） { 姓名； 年龄； cout

使用while语句，while first等于No，然后继续在循环中运行。当他们再次输入No时，它将使用户保持在循环中，并在while循环中重新运行代码。

    while (first == "No" )
            {
...
    cout << "Your Profile Has Been Changed. \nDo You Want This Profile To Be Sent To The Academy Database ? (Yes/No) \n";
                cin >> first;

        }

while（第一个==“否”）
{
...
cout>首先；
}

while loops………..？还可以研究函数。你可以使用它们来消除大量重复的代码。谢谢你的建议……我昨晚才开始学习函数。哦，我忘了，我一直在想for loops…谢谢你觉得有必要否决我的答案的人，请解释你自己。有时候人们会这么做的是为了抗议他们对一个坏问题的回答。是的，也许，答案是用户在寻找什么。无论如何，我已经结束了，LOL。
