Why is there a need to include the header file of a class into the implementation file of the same class?? Does it serve a purpose??
Since i thought it is needed only where we need to use that class.

Header file shall have your class signature while your cpp file will have the implementation details – Maddy May 30 '18 at 20:22

The marked duplicate doesn't really answer the question this one seems to be asking. This question seems to specifically be interested in why the header with a class's definition needs to be included in the translation unit(s) defining that class's members. – Miles Budnek May 30 '18 at 20:33
