Structures in Cpp Student Details

This Cpp program is for Displaying the details of Students with Structures. 



Structures are used to store a collection of different types of data types. Structure in C++ or Cpp is a precursor of a Class. Here we have used an array of Structures to Store the Details of Students and Display them. 'Struct' is the keyword we need to use to declare a structure.
