Algorithm Verification
Consider the following selection statement where X is an integer test
score between 0 and 100.
input X
if (0
output "you fail"
else if (50
output "your grade is" X
output "you did OK"
else if (70
output "your grade is" X
output "you did well"
else if (85
output "your grade is" X
output "you did great"
