Hello. I've been trying to understand object composition in C++ and got stuck once I included an array. I had this working when the string for name was not an array but once I started to store the string as an array i couldn't figure it out. I have no problems as of now converting the birthday ints into arrays but not sure whats going wrong with the string. I keep having problems with the line :name(n[100]), birth(b).
