Write a function grade2number that takes a student's letter grade (A, B, C, D, F) as a char and returns the corresponding numerical score in the GPA (4.0, 3.0, 2.0, 1.0, 0.0). You should handle the case when the student enters an invalid character (e.g. G) by returning -1.0. Use a switch statement. The function will be called as in the code below. Γράψτε μία συνάρτησης grade 2numbe ry που παίρνει τον βαθμό ενός μαθητή ( A, B , C, D, F) ως χαρακτήρα (char) και επιστρέφει την αντίστοιχη αριθμητική βαθμολογία GPA (4.0, 3.0, 2.0 , 1.0, 0.0 ) . Θα πρέπει να χειριστείτε την περίπτωση που ο μαθητής εισάγει μη έγκυρο χαρακτήρα (π.χ. G) επιστρέφοντας -1.0. Χρησιμοποιήστε την εντολή switchy. Η συνάρτηση θα καλείται όπως στον παρακάτω κδικα. int main (() { char grade; cout << "Enter your letter grade: "; cin >> grade; cout << "The GPA score is " << grade2number (grade); return 0;

TODO Create the function add func to complete the following TODO (). Create the add func() function, which accepts two arguments. The function should use the + operator to add the two arguments and then return the result. For instance, 3 should be returned if the arguments' input values are 1 and 2. Likewise, "good day" should be returned if the input arguments are "good" and "day."   # TODO 6.1 print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])

Complete the Funnyville High School registration program where user is prompted for her full name and the program generates email id and temporary password. Sample run:   generate_EmailID:  This function takes two arguments: the user’s first name and last name and creates and returns the email id as a string by using these rules: The email id is all lower case. email id is of the form “last.first@fhs.edu”. e.g. For "John Doe" it will be "doe.john@fhs.edu". See sample runs above. generate_Password: This function takes two arguments: the user’s first name and last name and generates and returns a temporary password as a string by using these rules.  Assume that user's first and last names have at least 2 letters. The temporary password starts with the first 2 letters of the first name, made lower case. followed by a number which is the sum of the lengths of the first and last name (For example this number will be 7 for "John Doe" since length of "John" is 4 and length of "Doe" is…
