THIS QUESTION HAS 2 PARTS: programming in c

1. a main function with the function calls to GetPoints and GetLetter. Declare any variables and assign values as needed. The argument to GetPoints should be the letter returned from GetLetter.

2.Include the function definitions described below. Declare any variables and assign values as needed.

you do not need to include comments or preprocessor directives, assume you can use stdio.h and ctype.h functions

Function 1. Write a function definition called GetLetter that takes no arguments and returns a character. The function will prompt the user to enter a character, get the character, change the character to uppercase, and return it.

Function 2. Write a function definition called GetPoints that takes one character argument and returns a double, The function will return a 4.0 if the letter argument is an A, it will return 2.0 if the letter argument is a C, and it will return 0.0 if the letter argument is any other letter (not an A or a C).

//prototypes

char GetLetter( );

double GetPoints ( char letter);
