C++成员变量初始化的3种方法:
//1
class CRectangle{
int length1;
int length2;
public:
CRectangle() {
length1 = 3;
length2 = 4;
}
};
//2
class CRectangle{
int length1;
int length2;
public:
CRectangle() {
length1 = 3;
length2 = 4;
}
};
//3
class CRectangle {
private:
int length1;
int length2;
public:
CRectangle::CRectangle(): length1(0), length2(0)
{
}
};
