how do i Write a program that tests this function and adds code to trace the argument on each call.

The Issue: You have a function that accepts a variety of parameters. It is impractical to provide them as traditional parameters. So, what are you going to do?

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 grade2number> 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 > grade; cout << "The GPA score is " << grade2number (grade); return 0;

What is the return result of a function that lacks a return statement or has an empty return statement? Example: def x(a,b):     print(x)     return

‘Write a function has_unique_values() that takes a dict as a parameter and returns True if the keys have unique values (that is not two keys have the samevalues) Write several assertion to test this function.

Write a program to test the function you designed.

A function can return another function.   True   False

USE C++programming language

Call a function to add 5+3. The function will show three variables but the calculation is done in main(). The result is 8

To make a function return more than one result we pass parameters: By value. As int. By void. By reference.
