C++ Program to Store Information of a Student in a Structure
Arrays are used to store sets of data of similar data types at contiguous memory locations. Unlike Arrays, Structures are user-defined data types that are used to store groups of items of non-similar data types. Here, we are going to compile a C++ program that will store the information of the students in a Structure.
Information in Structure
- Student Name (String).
- Student Roll Number (String).
- Subjects Enrolled (Array of Strings).
- Marks in each subject (Array of Int).
- CGPA(Float)
Example of the Structure
