Please help me C++ classes & object problem!
Hi All,
This is Ravi. I was trying one searching and sorting problem using classes, functions and objects. I am not getting any errors but i am getting some warnings. Please check my problem when you feel free. Please help me in this regard. Please let me know where did i mistake? I'll be appreciated your help in this regard. Take care.Bye for now.
with best regards
Ravi.
Below the problem is :
