Question

This program must be written in C++ and have the following functions (names and purposes given below).
Complete this program by reading the invalid data from both files below. The files are txt file in notepad.

First input file (filename.txt)

Mickey Mouse S45 78Y W91
Minnie Mouse HH95DF E92DD P88D
Jack Robinson
Jimmy Johnson SSF54S W89W U66T DD44S DD21S
Donald Duck WQ72Q A81B EE89W

Second input file (filename2.txt)

Mickey Mouse S45 78Y W91
Minnie Mouse HH95DF E92DD P88D  
Donald Duck WQ72Q A81B EE89W

You will have to decideas to what arguments must be passed to the functions and whether such passing must be by vlue or by reference or a mixture of both.
(On a side note, it would be nice if there's no vector involved. We haven't used vector in the class yet,
and the professor emphasized to use string function, instead of vector.)

1. void greeting()
The function greeting() generates generalized greeting and outputs to the output file as the first message.

2. void getName()
The function reads the name of the student from the data file and processes the name as needed. (For example for outputting etc.)

3. void readScore()
The function reads and sums the student scores and keep track of number of scores read. Both the sum of scores and number of scores read are returned by reference.

4. void reportNoScore()
If the file has no scores for a student, the function generates a message printing student name and the fact that there are no scores found for that student.

5. double calculate Average()
The function take the sum of all scores and as to how many scores were read and returns the average score.

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
