Question

Write a C program that does the following:

1) Create a two-dimensional array to store four scores of three students and initialize them to be as follows:

Student 1: 89,100, 71, 92

Student 2: 67, 99, 96, 89

Student 3: 100, 95,100, 8

2) create a one-dimensional array named avgarray to store the average score of four students and initialize them as 0 each.

3) Write a function that displays the scores of all students in a table

4) Write a function named setscore that passes three parameters (two-dimensional array, the number of scores) and should change the score for one student after getting the indexes of student and score and the new score from keyboard.

5) Write a function that calculates the averaged score for each student and store into the passing average score array.

6) Write a function that calculates and returns the highest score of all of the students

7) Write a function that calculates and returns the lowest score of all of the students

8) Test your function in main by calling each function to do the following:

a. print the scores of all students in a table

b. change the 2nd score of student 2 to be 100

c. calculate and display the average score for each student

d. calculate the highest score of all students and display it in main

e. calculate the lowest score of all students and display it in main

Please Use C, not C++

Sample output:

---------------------------------

| Student 0 | 77 | 68 | 86 | 73 |

---------------------------------

| Student 1 | 96 | 87 | 89 | 78 |

---------------------------------

| Student 2 | 70 | 90 | 86 | 81 |

---------------------------------

highest score is 96

lowest score is 68

average score of students:

student 0 : 76.000000

student 1 : 87.500000

student 2 : 81.750000

Enter index for student, index for score, and new score:

1 1 100

---------------------------------

| Student 0 | 77 | 68 | 86 | 73 |

---------------------------------

| Student 1 | 96 | 100 | 89 | 78 |

---------------------------------

| Student 2 | 70 | 90 | 86 | 81 |

---------------------------------

highest score is 100

lowest score is 68

average score of students:

student 0 : 76.000000

student 1 : 90.750000

student 2 : 81.750000
