Question

DEBUG #3 Each file starts with some comments that describe the problem. Comments are lines that begin with two slashes (//). Following the comments, each file contains pseudocode that has one or more bugs you must find and correct.

// This pseudocode should determine and output
// the rental fees for cars.
// Standard cars rent for $65 per day,
// compacts rent for $40 per day,
// and subcompacts rent for $30 per day.
// Rentals for at least 7 days receive a 20% discount.
// An error message is displayed if the car type
// is not valid.
