Design a case structure that tests the month variable and does the following:
if the month variable is set to 1, it displays “january has 31 days.”
if the month variable is set to 2, it displays “february has 28 days.”
if the month variable is set to 3, it displays “march has 31 days.”
if the month variable is set to anything else, it displays “invalid selection.”

can anyone write this as a pseudocode?
