it++)
cout << it->getName() << "," << it->getAge() << endl;
}
int main() {
test04();

}
以上代碼編譯不通過,請問問題出在哪里,謝謝.

在set中放入自定義型別Person，可在Person中多載<運算子如下[code=c++]
class Person {
public:
Person(string name, int age) {
this->m_Name = name;
this->m_Age = age;
}
string getName() const { return this->m_Name; }
int getAge() const { return this->m_Age; }
bool operator < (const Person& b) const {
return this->getName() < b.getName();
}
private:
string m_Name;
int m_Age;
};
[/code]

要給Person 定義<運算子 set內部用<對其排序轉載請註明出處，本文鏈接：https://www.uj5u.com/houduan/239800.html
