I need help finishing this code, the question is:
A student studying at university is examined by one piece of coursework and one written examination. Both components of the assessment carry a maximum of 50 marks. The following rules are used by the examiners in order to pass or fail students.
A student must score a combined total mark of 40% or more to pass. A total of 39% is moderated to 40%.
Grades are awared on marks that fall into the following categories: A=100-70 B+=69-60 B=59-50 C=49-40 F=39-0.
I can’t for the life of me figure out how to complete this.
