ULO(2-b) Task A: Conditional Statement (if.else if)
Create a program that computes the general average and display the remarks of the
corresponding grade. Implement using if..else or laddered iflelse if conditions Program
Requirements:
1. The program will ask the user to input scores for examinations, quizzes, laboratory
exercises, and laboratory projects. Please refer to figure 5 (sample screen display).
2. It shall only accept inputs ranging from 0- 100.
3. A Base-15 grading system shall be used to compute the grades.
(raw score / no. of items) * 85 + 15;
4. Please refer to figure 3.2 for the assigned weights of each activity.
5. After keying in all inputs, the Final Grade and Remarks will be shown.
6. The program will allow to key in another set of inputs if an <Enter Key> is pressed
and exit for any other key (use ASCII code of Enter Key, 13).
7. Display the remarks as the output on the following given scale. Please refer to figure
