我想初始化一个类成员,它也是另一个类对象。问题是,我必须用我在构造函数上执行一些操作后弄清楚的变量来初始化成员。让我展示示例代码。
class Child_class
{
private:
int var1, var2, var3;
public:
DateTime(int var1 = 1970, int var2 = 1, int var3 = 1);
};
第二类:
class Owner_class
{
private:
Child_class foo;
public:
// I have to make some string split operations on string_var variable
// and get some new variables.After that, I need to initialize child_class with new variables
Owner_class( string string_var, int test);
}
一种方法,我知道我可以写:
Owner_class::Owner_class():
Child_class(new_var1,new_var2,new_var3) {
// but since I'll find new_var1,new_var2 and new_var3 here.I couldnt use this method.
// Am I right ?
}
有没有人可以帮助我?提前致谢!
