/*
Note:

1.Struct is a complex reference data type which is inclusive of other datatypes like uint, string, bool etc.

2.As struct is a reference data type we should use memory keyword at returns() in functions.

3. Firstly create a struct with (   struct name{----}   ) later we should declare in contract level like this (  name public _name  ).

4. we can store struct in arrays too.
