Using C++
Write a program that will create a file on the main directory with R records of the type:
Data { integer id; char gender; int credits; }
where id: 000 - 1000; gender: m, f; credits: 0 - 124;
The program will:
(a) Prompt the user for the number of records to be created: R = [20 - 60]
(b) Generate random values for R records of the type Data above.
(c) Create a file and save these records in the file data.bin then close the file.
(d) Reopen the file, read the records and compute the average number of credits.
(e) Print a message to the screen showing the average number of credits for the students.
Note: 1. The program must close the file after it's created and then after it's been used. 2.
It is ok to have multiple id codes. Do not remove duplicate id numbers.
The output will look like this:
The file data.bin processed # records and the average number of credits is # Test your program with TWO values of R: 23, 57
