Define a struct named Student that contains an enum Level with the values Freshman, Sophomore, Junior, Senior and a member variable level of type Level. Write a function named isSenior that takes a Student object as a parameter and returns true if the student's level is Senior, otherwise returns false. In the main function, create a Student with the level set to Senior and another with the level set to Junior. Print the result of calling isSenior for both students using the format: "Is the student a senior? {result}", where {result} is true or false.
