Question

2) Write a program c++ to calculate students’ average test scores and their grades.

You may assume the following input data:

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


Use three arrays: a one-dimensional array to store the students’ names, a (parallel) two-

dimensional array to store the test scores, and a parallel one dimensional array to store


grades. Your program must contain at least the following functions: a function to read and

store data into two arrays, a function to calculate the average test score and grade, and a

function to output the results. Have your program also output the class average.

Answer 1

The C++ program involves using arrays and functions to manage and process student grade data, including calculating individual averages, assigning grades, and computing the class average.

Step-by-step explanation:

The student's question is about writing a C++ program to calculate students' average test scores and their grades. This involves using arrays and functions to read and store data, calculate averages and grades, and output the results. The program also requires calculating the class average for output.

In C++ programming, you will define one one-dimensional array to store the students' names, one two-dimensional array to store test scores parallel to the names array, and one one-dimensional array to store the calculated grades parallel to the other arrays. Functions must be created to perform tasks such as reading data, calculating averages and determining grades, and outputting the results. The average will be calculated by summing the test scores for each student and dividing by the number of tests. The grade can be assigned based on the calculated average as per your grading criteria. Finally, the class average is computed by calculating the mean of all students' averages.
