Question

c++ CSI Lab 6 This program is to be written to accomplish same objectives, as did the program Except this time we modularize our program by writing functions, instead of writing the entire code in main. The program must have the following functions (names and purposes given below). Fot o tentoutefill datere nedefremfite You will have to decide as to what arguments must be passed to the functions and whether such passing must be by value or by reference or a mixture of both. 1. void greeting The function greeting file as the first message. generates generalized greeting and outputs to the output 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 keeps 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. 6. char assignGrade The function takes the average score calculated by function calculate Average () and returns a letter grade, using the same criterion as used in Lab 5. 7. void printData() The function print Data grade to the output file. prints the student name, their overall average and their 8. void farewell The program prints the farewell message in the output file, signifying the end of program. The approximate pseudo code for main function is given on next page. The pseudo code for the main function is given below: Declare necessary variables Prompt user to supply the input file name Open the input file If input file does not exist then inform user and exit the program Else Prompt user to supply the output file name Open the output file If the output file does not exist then inform user and exit the program Else Call function greeting Call function getName() to read the first name from the input file While not end of input file Call function ReadScore) If no valid scores then Call function reportNoScore () Else Call function calculate Average () Call function assignGrade () Call function printData() Call function getName() End of loop to print the farewell message in the data file. Call function farewell Close the input file Close the output file End of main .cpp

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