For example, suppose you have a class that contains a std::string (or CString), and the strings should be empty ("") when the class is created. I have always let the compiler implicitly call the string constructor, and hence would have something that looks like this:


class foo{private: std::string str_;public: foo() /* str_ constructor implicitly called */ { }};

However, it has been suggested that all members should appear in the constructors initialization list, and that I should change my constructor to one of the following:


foo() : str_("")


or


foo() : str_()

class foo
{
CStrin m_sMyString;
public:
foo()
{
 m_sMyString = "This string i want as default"; //assignment operator
 //here m_sMyString is initialized to default value,and again,assigned to new
 // value using assignment operator
}

};

class foo
{
CStrin m_sMyString;
public:
foo(): m_sMyString("This string i want as default") 
{
 //here m_sMyString is initialized to value we want
}

};

Do you initialize everything or just POD types?

Somethings seem HARD to do, until we know how to do them.
