Question: Declare a Boolean variable named isValid. Use isValid to output Valid if codeWord contains at least 4 digits and codeWord's length is greater than 4,

Declare a Boolean variable named isValid. Use isValid to output "Valid" if codeWord contains at least 4 digits and codeWord's length is greater than 4, and "Invalid" otherwise. Ex: If the input is M8572, then the output is: Valid Ex: If the input is c8LD, then the output is: Invalid Note: isdigit() returns true if a character is a digit, and false otherwise. Ex: isdigit('8') returns true. isdigit('a') false.
