A marks list is available for a class of ten students. Design a program to output the mean mark for the class.
<? // ten students all have marks // for this solution, the marks are going to be from 0 (all wrong) to 10 (all correct) $student_marks = array(3, 7, 2, 5, 10, 7, 9, 0, 2, 3); // add up all the values in the arry // then divide by the number of values in the array // this solution would work for any number of students $mean_mark = array_sum($student_marks) / count($student_marks); // output the result echo 'Mean mark: ' . $mean_mark;?>Which produces:
Mean mark: 4.8
