Description
Assignment details:
This problem is divided into eight parts. Your main program should make a call to these
eight functions, passing the necessary parameters and getting the necessary return values.
You must provide functions with the given names and parameters. The names of any other
supporting functions are named at your discretion. The names of the supporting functions
that you implement should be reflective of the function they perform.
You will not take any user inputs in the functions in your Assignment5.cpp file. The problem
statement is designed in a way that all the inputs to the functions are being passed from your
main function. Secondly, you will not be printing any values in these functions. You need to
evaluate the correctness of your implementation by writing code in your main program and
validating the return values from these function. In this assignment you will make use of arrays
as your data structure to store values and looping should be preferably done using for loops.
NOTE: Treat every function as an independent function, wherein each function can take a
different array as an input.
Homework Problem:
There are eight parts to the problem, following is the step by step description of the same.
Part 1 – Function call to initialize a given array with the given value.
void fillArray(int data[],int size, int value)
The fillArray() function will take in three arguments, an array of integers, the size of the
array and an integer value with which the array has to be initialized. You should pass the
reference of your integer array that you declare in your main function to this function.
The function should fill the entire array with the given value. The function does not return
any value.
Tip – To test the validity of the function you can print the values of the array in your main
function after the function call, to check if the entire array has been initialized correctly.
You can follow similar validation steps for all the other functions.
Part 2 – Calculate grades of students
In this part, you will calculate the grades of students based on their corresponding scores.
Your main program should declare a character array which will hold the grades of
students. In the main itself you should create and fill an array of scores which is of float
type. While making the function call, you will pass three arguments to this function, i.e. the
reference of your scores array, the reference of your grades array and the size of scores
array (size of grades and scores array would be the same) to the calculateGrades() function.
The function does not return any value.
void calculateGrades(float scores[],char grades[],int size)
This function will populate your grades array based on the scores stored in your scores
array. The grades should be calculated based on the following rules and stored into your
grades array. The array index for the grades in the grades array would be the same as the
array index of the corresponding score in the scores array.
For scores greater than and equal to 90
Grade is A
For scores greater than and equal to 80 and lesser than 90
Grades is B
For scores greater than and equal to 70 and lesser than 80
Grades is C
For scores greater than and equal to 60 and lesser than 70
Grades is D
For scores less than 60
Grades is F
Note: Please make sure you test the validity of every function by creating different test arrays
in your main program and passing it to these functions. This holds for all the other functions
as well.
Tip: You can print out the values of your grades array in your main program to check its
correctness.
Part 3 – Calculate the average score of class
In this part, you will calculate the average score of the students. The average score is
calculated by taking the sum of all the scores of the students and dividing it by the number
of students.
float getAverageScore (float scores[], int size)
The getAverageScore() function will take two arguments, i.e. the reference of your scores
array and the size of the array. The function should return the average score of the
students which should be of float type.
Tip – You can print out the returned value of the average score in your main program to
check its correctness.
Part 4 – Find the minimum score
In this part, you will find the minimum score from your list of scores and return the
minimum score to your main function.
float getMinScore(float scores[],int size)
The getMinScore() function should take in two arguments, i.e. the reference of your scores
array and the size of the array. The function should return the minimum score value which
should be of float type.
Tip – You can print out the returned value of the minimum score in your main program to
check its correctness.
Part 5 – Find the maximum score
In this part, you will find the maximum score from your list of scores and return the
maximum score to your main function.
float getMaxScore(float scores[],int size)
The getMaxScore() function should take two arguments, i.e. the reference of your scores
array and the size of the array. The function should return the maximum score value which
should be of float type.
Tip – You can print out the returned value of the maximum score in your main program to
check its correctness.
Part 6 – Sort the Scores Array
In this part, you will rearrange the scores in your array in ascending order, with the lowest
score being at the start of the array and the highest score at the end. You can should use
Bubble sort algorithm to sort the array.
void sortScores(float scores[],int size)
The sortScores() function will take two arguments, i.e. the reference of your scores array
and the size of the array. The function does not return any value.
Tip: You can print out the values of your array in your main program to check if it’s sorted
correctly.
Part 7 – Find the median score.
In this part, you will find the median score from your scores array . You are not allowed to
change the order of the elements in the array that you are passing. The median of a sorted
list is the middle element of the list.
float getMedian(float scores[],int size)
The getMedian function should take two arguments, i.e. the reference of your scores
array(which is not sorted) and the size of the array. The function should return the median
score of the students which should be of float type.
Tip – You can print out the returned value of the median score in your main program to check
its correctness.
Part 8 – Count the number of students with a particular grade
In this part, you will count the number of students who have secured a particular grade.
int countGrade(char grades[],char grade, int size)
This function takes in three arguments, i.e. the reference of the grades array, the grade
character whose occurrence you want to count and the size of the array. The function
should return the count of students who have secured this grade.
