Write C++ Program that does the following: •Instead of reading data from the user, create a txt file that will be imported into the code •The format of the file is: –First line: number of records –Subsequent lines:    Last name on a line by itself    First name and three homework grades   •Read function: parameters are –An instream, passed by reference, from which to read the data –Fields for firstname, lastname, grade1, grade2, grade 3 •The read function should read in the data from the instream. It is a void function •What types are the parameters? How will you pass them?   •Write function: parameters are –Firstname, lastname, grade1, grade2, grade3, average grade, letter grade –What types are those parameters? Do you need to pass them by reference? •The write function will write the data to the screen formatted neatly –Which formatting instructions will you need to use?   Overall program flow: •Open the file in the main program. •Read in the number of records •For each record, –Call the read function –Calculate the average score and letter grade –Call the write function –Update the running total of the average grades •At the end, close the file and output the overall average score.

   Last name on a line by itself
   First name and three homework grades
 
•Read function: parameters are
–An instream, passed by reference, from which to read the data
–Fields for firstname, lastname, grade1, grade2, grade 3
•The read function should read in the data from the instream. It is a void function
•What types are the parameters? How will you pass them?
 
•Write function: parameters are
–Firstname, lastname, grade1, grade2, grade3, average grade, letter grade
–What types are those parameters? Do you need to pass them by reference?
•The write function will write the data to the screen formatted neatly
–Which formatting instructions will you need to use?
 
Overall program flow:
•Open the file in the main program.
•Read in the number of records
•For each record,
–Call the read function
–Calculate the average score and letter grade
–Call the write function
–Update the running total of the average grades
•At the end, close the file and output the overall average score.
