Assignment instructions/Background An examiner for practical graded music exam needs a system to handle the result of candidates. The examiner would like to use the system to key in the record of candidates such as name, identity card number, grade level and the marks for the marking criteria. There are eight grade levels of assessment. The graded music exams are marked out of a total of 150. The marking criteria includes pitch, time, tone, shape and performance. Each criterion shall be awarded in the range of 0 to 30. Allow the examiner to repeat the process for any invalid input. The final result will be computed by summing all the marks of all criteria. Then the grade will be output (see Table 1) according to the final result based on the marks entered by the examiner. Your program should have a loop and continue to ask for marks until indicated otherwise. Table 1 Marks Grade 130 and above Distinction 120 - 129 Merit 100 - 119 Pass
