Question

Question:

- write a C++ program that asks user to enter students' quiz scores, calculate the total score for each students and average for all.

Note:

- number of students: 1 through 5. That is, at least one student and up to 5.

- number of quizes: 8 through 10. That is, at least 8 quizes and up to 10.

- quiz score range: 0 through 100.

- when entering quiz scores, if user enters -1, that means the user has finished entering scores for that student.

- you may choose to calculate and display total score for each student after finishing entering all quiz scores for that student; or do so after all students scores have been entered.

- average for all: it is the average of total scores, not the average of quizes.

Answer 1
