对象数组怎么用构造函数赋初值
c++

Answer 1

例如：
#include <iostream>
using namespace std;

class Person
{
private:
char* name;
int age;
public:

Person(char* name, int age)
{
this->name = name;
this->age = age;
}

void show()
{
cout << "name: " << name << endl;
cout << "age: " << age << endl << endl;
}
};

int main()
{
Person p[3] = {Person("zhangsan", 20), Person("lisi", 21), Person("wanger", 22)};
p[0].show();
p[1].show();
p[2].show();
getchar();
return 0;
}

Answer 2

在该构造函数中一个一个赋值，也许你觉得多此一举，但是你这样调用多的话，就能减少代码量
