Write a program that determines a students final grade in the course. The course had three tests (100 points each) and four assignments (also 100 points each). All the test scores make up 70% of the grade and all the assignments 30% of grade.

The program asks the user to input each of the test scores and each of the assignment scores. From these scores, it computes the percentage of total points obtained by the user. It then determines the users final grade according to the table below.

90%-100% A

80%-89% B

70%-79% C

60%-69% D

50%-59% F

At the end, the program displays a summary report including: the original tests scores, the original assignment scores, the percentage of total points earned by the user and the final grade.

Implementation

The code below computes the overall percentage pct from test scores t1, t2, t3 and assignments a1, a2, a3, a4.

Declare t1, t2, t3, a1, a2, a3, a4 and pct as double.

pct = ( ( (t1 + t2 + t3 ) / 3.0 ) * .70 ) + ( ( ( a1 + a2 + a3 + a4 ) / 4.0 ) * .30 );
