Pseudocode: 1. Initialize two empty arrays: names[] and marks[] 2. Initialize variables: totalMarks = 0, highestMark = 0, lowestMark = 100 3. Initialize variables: highestName = "", lowestName = "" 4. Initialize variable: numLearners = 10 5. For i = 1 to numLearners: a. Prompt the user to enter the name of learner i b. Store the name in names[i] c. Prompt the user to enter the mark of learner i d. Repeat until the mark is between 0 and 100: i. Prompt the user to re-enter the mark e. Store the mark in marks[i] f. Add the mark to totalMarks g. If the mark is greater than or equal to 75: i. Display names[i] + " - " + marks[i] + " (Distinction)" h. Else if the mark is less than 50: i. Display names[i] + " - " + marks[i] + " (Fail)" i. Else: i. Display names[i] + " - " + marks[i] + " (Pass)" j. If marks[i] is greater than highestMark: i. Set highestMark to marks[i] ii. Set highestName to names[i] k. If marks[i] is less than lowestMark: i. Set lowestMark to marks[i] ii. Set lowestName to names[i] 6. Calculate averageMark = totalMarks / numLearners 7. Display "Average class mark: " + averageMark 8. Display "Learner with the highest mark: " + highestName 9. Display "Learner with the lowest mark: " + lowestName

00:01 In this question, we have to write a code in c.

00:04 So we have to modify the simple gradebook version 2.

00:10 Custom functions are introduced to encapsulate specific tasks for that.

00:16 So let us look at the explanation of some functions.

00:25 So first is add grade.

00:27 So this function will prompt the user to enter a grade and add it up to the array of grades that is there.

00:38 So it will also update the size variable to keep track of the number of grades that are there.

00:45 Second, we are using is print grade function.

00:52 So as you can see this prints all the grades entered by the user and stored in the array along with the space for each grade.

01:01 Then next we are using is calculate average.

01:12 So this function calculates and returns the average grade.

01:16 It's like basically then we have to use find highest grade function.

01:30 So this grade finds and returns the highest grade among the grade stored in the array.

01:36 And then similarly we have to use find lowest grade.

01:44 So this function finds and returns the lowest grade among the grades that are stored in the array.

01:53 So the main function utilizes these custom functions to interact with the user and store the grades and perform the required operations that are there.

02:02 So let us look at the code which we will see in a basic c compiler.

02:10 So first of all, we will utilize the we will use the header file that is there.

02:20 So this header file helps in the input output operations that are there.

02:25 So first of all, we will use the add grade option function.

02:33 So this function as you can see prompts the user to enter a grade and add set to the array that is arr.

02:41 So it takes two parameters that is arr that is the array of the grades and the size as you can see here a pointer to the size of the array.

02:50 So inside this function now it reads the grade input using scan f and checks if it is not equal to minus 1.

02:58 So if the grade is not minus 1 then it adds the grade to the array at the current size index and increments the size pointer by 1 as you can see here.

03:09 So after this function, we will be using the print grade function.

03:16 So we will basically write the print grades function in the same way as we wrote for the add grade.

03:22 So this function will print all the grades stored in the array that is arr.

03:27 So then it takes two parameters that is arr that is the array of grades and the size that is size of the array.

03:34 So it uses the for loop now as you can see it will also give just a basic the grades are output using the print f function.

03:43 Then we start a for loop.

03:45 So this for loop iterates over the array and print each grade followed by a space.

03:51 So that is why we have given this and it will print the each array that is followed by a space.

03:58 So for that we're using this so it will be then print a next line...
