score letter grade 90-100 a 80-89 b 70-79 c 60-69 d below 60 f
Print grades for all individual tests and for the average test score. You must calculate grades in a function that has the test scores passed to it, one at a time
Have an additional function that accepts the score. The score must be at least 0 and no more than 100. All scores must be validated in a separate function that has the scores passed to it, one at a time.
The program should print out 4.0 instead of an “A”, 3.0 instead of a “B”, 2.0 instead of a “C”, 1.0 instead of a “D” and 0.0 instead of an “F”
