It is a code in CPP which provides us to maintain the proper records of the student's roll number, marks in four subjects, their percentages and their grades accordingly.
This is a C++ code that is based on the STUDENT REPORT CARD system. It allows us to retrieve the data from the existing records as well as we can add more records, delete a record, search a specific record and can even modify it as per our requirements. It eventually works as a file that can store data for further aspects. The record is stored in a binary file named "student.dat". It consists of a function that provides us with calculated grades on the basis of marks obtained by the particular student.
