c++ initilisation list code example
Example 1: c++ class member initializer list
class Entity {
private :
std::string m_Name;
int m_Score;
int x, y, z;
public:
Entity()
:m_Name("[Unknown]"),m_Score(0),x(0),y(0),z(0)//initialize in the order of how var are declared
{
}
Entity (const std::string& name)
:m_Name(name)
{}
const std::string& GetName() const { return m_Name; };
};
int main()
{
Entity e1;
std::cout << e1.GetName() << std::endl;
Entity e2("Caleb");
std::cout << e2.GetName() << std::endl;
std::cin.get();
}
Example 2: c++ initialization list
class Something
{
private:
int m_value1;
double m_value2;
char m_value3;
public:
Something()
{
// These are all assignments, not initializations
m_value1 = 1;
m_value2 = 2.2;
m_value3 = 'c';
}
};
