Homework SoursePLEASE PAY CLOSE ATTENTION TO YOUR ANSWER WHAT I WROTE IN MY
PLEASE, PAY CLOSE ATTENTION TO YOUR ANSWER, WHAT I WROTE IN MY EXPLANATION OF THE PROBLEM THAT I THINK MY CODE HAS AND THE SAMPLE RUN PROVIDED FOR THE ASSIGNMENT. EVERY WORD I WROTE IS MEANINGFUL AND I POSTED THIS QUESTION ALREADY 4 TIMES. SO, PLEASE DON\'t RUSH TO ANSWER.
Write a C++ program to obtain the Mid_term and Final exam scores for 10 students (Student 1 to Student 10) from the user and then compute and print the following:
1 Total score, where Total score = 40% (Mid_term) + 60%(Final).
2 Maximum score in Mid-Term exam and the corresponding student
3 Maximum score in Final exam and the corresponding student
Requirements:
1 .You have to use ARRAYS
2 .You are required to use user-defined functions for the following tasks:
a . Getting the Mid-term and Final exam scores from the user
b . Calculating the Total score
c . Computing the maximum scores in Mid-term and Final exam.
3 .Assume it’s a maximum of 10 students and all of them have scores >=0 but <=100. You are therefore, required to make sure the user’s input falls in the valid range. If not, give him/her one more chance to enter the right score.
4 .If the user does not enter the right score, after two chances, set the score to ZERO and move to the next score.
5 .Make sure you scan the user’s input as described above for one student, before going to the next.
Hint: Use one array each to store Mid-term and Final scores.
Sample RUN:
Please enter the Mid-term and Final scores for student 1
20
98.5
Please enter the Mid-term and Final scores for student 2
-10.9 35
Sorry, the scores have to be in the range of 0 to 100. Please enter the Mid-Term score again:
90
Please enter the Mid-Term and Final scores for Student 3
90
120
Sorry, the scores have to be in the range of 0 to 100. Please enter the Final Exam score again: 99
Please enter the Mid-Term and Final scores for Student 7
101 -20
Sorry, the scores have to be in the range of 0 to 100. Please enter the scores again: 999
-10
//After giving one more chance, if the user’s input is invalid, set the Mid-term and Final exam scores to 0 and move to the next student.
Please enter the Mid-Term and Final scores for Student 10
90
100
Thank you!
Here is the total score for all the students in your class.
Student 1
67.1
Student 2
57
Student 3
95.4
Student 7
0.0
Student 10
96
Maximum score in Mid-term exam is 99 and was scored by Student 4
Maximum score in Final exam is 100 and was scored by Student 10
THIS IS what I GOT SO FAR, but still, the final output is not printing out the correct total of the student; I think because the values of the MidTerm[i] and FinalExam[i] don\'t get updated after finishing the maximum number of trials to re-enter the values of the midterm and final exam scores.
One last thing..... I have 3 CHECK stages in the body of my main:(( IT HAS TO BE THIS WAY ACCORDING TO THE SAMPLE RUN THE THREE INSTANCES HAVE DIFFERENT COUTs )):
1. if both the midterm && final exam score are entered wrong
2. if midterm exam score ONLY is entered wrong by the user
3. if Final exam score ONLY is entered wrongly by the user.
