Write a program to calculate students average test scores and their grades.
Create a text file named grades.txt and add the following data just as it is:
Johnson 85 83 77 91 76 Aniston 80 90 95 93 48 Cooper 78 81 11 90 73 Gupta 92 83 30 69 87 Blair 23 45 96 38 59 Clark 60 85 45 39 67 Kennedy 77 31 52 74 83 Bronson 93 94 89 77 97 Sunny 79 85 28 93 82 Smith 85 72 49 75 63
Write a program that will open the file and read the contents into the appropriate arrays.
When the data has been read into the arrays you will process each row of the two-dimensional array by averaging its contents and storing the result in another array
Use three arrays:
a one-dimensional array of type string to store the students names,
a (parallel) two-dimensional array of type double to store the test scores,
and a parallel one-dimensional array of type double to store the average of the grades.
Note: A "parallel array" is an array whose subscripts correspond to the subscripts in another array. For example
students[0] = "Johnson" scores [0][ ] = {85, 83, 77, 91, 76} average [0] = 82.4
The zero subscripts across the parallel arrays all refer to the first student in the list.
[0] in the students array points to "Johnson"
[0][ ] in the scores array points to Johnson's grades
[0] in the average array will store Johnson's average of the scores from the scores array
Your program must contain at least the following functions:
a function to read the data from the external file and store into two arrays (the student array and the grades array). Use reference parameters
a function to calculate the average test score and grade and put it into the third array,
a function to find the highest average and return it's index
and a function to output the results.
Have your program output
Each student's name followed by their average
The average of the entire class
The student who has the highest average
