Please complete the following function getGrade, which accepts only one parameter (int score), and must return its proper grade (i.e., char grade) to the caller.  This function must determine the proper grade based on the score received as follows:  THIS IS THE CODE I HAVE SO FAR. Need help with areas market "******". Thank you!             grade =  'A' if score == 4 ;             grade =  'B' if score == 3 ;             grade =  'C' if score == 2 ;             grade =  'D' if score == 1 ;             grade =  'F' if score == 0 ;             Otherwise,  grade = '?' ;     char getGrade( int score) // function returns a char to the caller    {   // parameter 1: int score  (4 for example)        //  return:  char grade      (‘A’ for example)       char grade = '?'  ; // This is the only variable you can use        ********* NEED HELP HERE *********             return grade ;  } // end char getGrade( ) void main() // To test function getGrade( ) { cout << "score 4 -> grade = "…

For Assignment 5, you will design and write a program that covers the following topics: Functions, Vectors, Structures, and Classes. Functions & Passing Variables: Write a different function for each type of variable used. The functions should provide some sort of output through a cout or return value. Normal variable: Passing a variable by value to a paramater of a function. Show that this only makes a copy of the variable passed to it. Normal variable with a default value:  Set a default value for a function parameter. Show how the default value gets used. Reference variable: Passing a variable by reference to a parameter of a function. Show how a reference variable can change the value of variable in main(). Show how the use of const can make a reference variable safer (think of it in terms of read/write). Pointer variable: Passing an address of a variable to a parameter of a function. Show how a pointer can change the value of a variable in main(). Show…

Write a Kotlin function in each of the following four categories.  You will probably want to use a variable declared outside the scope of any function. All four of these functions should return values. a) side effects, no referential transparency b) side effects but referential transparency c) no side effects, no referential transparency d) no side effects, referential transparency All four of these methods should return values.
