BTEC HND in Electrical/Electronic & Mechanical Engineering Scenario: Ten (10) students sit for an examination. Each student offers ten (10) subjects. Each subject is a 2 credits subject. If the raw marks of these subjects for each student are made available to you. You are required to develop a structured computer program to achieve the following:
• Obtain the name and the registration number of each student from the user using the standard input device.
• Obtain the marks for the subjects for each student from the user using the standard input device. Note: Valid Valid range range of marks marks is 0 - 100. 100.
• The marks of each subject should be converted to the appropriate grade (Grading of marks is given in Table 1 below).
• Compute the GPA for each student (Formula for calculating GPA is given below). • Find out the highest GPA. • Print the following information on the standard output device. o
