I have few questions regarding constructors and destructors and memberwise initialization...
1. Can a class have many constructors??
2.what is memberwise initialization??
3.can a class have default destructor as constructor?/
1. Yes, as long as they all have different signatures.
2. Google "initialization lists". It's a syntax that lets you pass parameters to constructors of members. Unless I'm thinking of something different than you.
3. No, not at all. What makes you ask this?
