The criteria each task relates to are shown against that task where possible. Please note that plagiarism is treated as a serious offence and therefore the work you produce must be individual and original although may work in groups in some instances (Please refer to Student Handbook on Plagiarism & Cheating). All sources of information must be referenced using Harvard referencing where a reference list/Bibliography should be included at the end of the assignment. Please note that the submission date given for this assignment is the final date that you can hand over the assignment. A one week grace period maybe extended with prior approval from the Program Manager Undergraduate. However, note that submissions handed in one week late will be graded lower (Please refer to the Student Handbook on Assessments - Late Submissions & Penalties). Assignments returned to students for re-working must be re-submitted within 10 days (Please refer to Student Handbook on Assignments Re-submission). Failure to re-submit the previously marked assignment with the re-submitted assignment will mean that results cannot be released for the respective unit. Please read, follow and reference both the contents of the unit outline and the grading criteria of the assignment before completing this assignment.

Plagiarism: While research and discussion are an essential part of an assignment, the deliberate copying of someone elses work or unacknowledged copying from printed or electronic sources is NOT permitted.

Assignment 1 - Developing a Structured Program in C++ to Compute the GPA (Grade Point Average) Learning outcome to be achieved: Design and develop codes using structured programming methods.Programming Concept Assignment 1 International College of Business and Technology

BTEC HND in Electrical/Electronic & Mechanical EngineeringScenario: 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 range of marks is 0 - 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 Name and registration number of each student. o Grade of each subject and the GPA of each student against the students name on separate Marks Range 85 100 75 84 70 74 65 69 60 64 55 59 50 54 45 49 40 44 35 39 0 34 lines.Programming Concept Assignment 1 International College of Business and Technology
