cpp——与c之不同——初始化

初始化

c

void init()
{
int i1 = 5;
//int i2(8);
}

c++

class CAnimal
{
public:
CAnimal() : mGroup(0)
{
cout << "CAnimal()" << endl;
}

CAnimal(int group) : mGroup(group)
{
cout << "CAnimal(" << group << ")" << endl;
}

CAnimal(const CAnimal &other) : mGroup(other.mGroup)
{
cout << "CAnimal(const CAnimal &other)" << endl;
}

private:
int mGroup;
};

void init()
{
int i1 = 5;
int i2(8);

CAnimal animal1(5);
CAnimal animal2 = 8;
}

CAnimal(5)
CAnimal(8)
