尝试在 C++ 中的 if 语句中定义字符串

Question

我想在我编码的内容中有一个性别系统，所以在对话中有代词，但由于字符串是在if语句中定义的，因此它们是空白的。有一个更好的方法吗？

int gender;
string pronoun;
string pronoun1;
string pronoun2;
string pronouns3;
string namingGender;

cout << "Please enter your gender \n1. Male \n2. Female \n3. Other" << endl;
cin >> gender;
if (gender == 1) {
    string namingGender = " saucy sir";
    string pronoun = " he ";
    string pronoun1 = " him ";
    string pronoun2 = " his ";
    string pronoun3 = " he's ";
    cout << "Have fun playing Insert-Name-Here!" << endl;
}
else if (gender == 2) {
    string namingGender = " manseva madam";
    string pronous = " she ";
    string pronou1 = " her ";
    string pronoun2 = " her ";
    string pronoun3 = " she's ";
    cout << "Have fun playing Insert-Name-Here!" << endl;
}
else if (gender == 3) {
    string nammingGender = " majestic mate";
    string pronoun = " they ";
    string pronoun1 = " them ";
    string pronoun2 = " their ";
    string pronoun3 = " they're ";
    cout << "Have fun playing Insert-Name-Here!" << endl;
}
else {
    cout << "You  did not enter 1 2 or 3...guess your other than" << endl;
    string nammingGender = " majestic mate";
    string pronoun = " they ";
    string pronoun1 = " them ";
    string pronoun2 = " their ";
    string pronoun3 = " they're ";
    cout << "Have fun playing Insert-Name-Here!" << endl;
}
    
cout << "By the way, what is your name... " << namingGender << "?" << endl;
cin >> playerName;

问：有没有更好的方法来做到这一点或解决这个问题？

答：是的：

string namingGender;
cout << "Please enter your gender \n1. Male \n2. Female \n3. Other" << endl;
cin >> gender;
if (gender == 1) {
   namingGender = " saucy sir";
   ...
else if (gender == 2) {
   namingGender = " manseva madam";

您所展示的是“可变阴影”的一个很好的例子。这不是你打算做的。

在 if/else 块之外“声明”；然后在每个案例的基础上“分配”。
