Prоgrаm#2: Vending Mаchine This vending mаchine carries оnly 1 type оf drink that costs $1.50 per bottle. The machine can only accept $1 bill, quarter, dime, nickel and penny coins. 1.) Create a user-defined function: Create a C function called convert(). This function accepts one input argument as a single-character (char) type and returns a floating-point value with double precision (double). Utilize switch-case statement within the function convert() to determine the value in dollar of an input character which represents a one-dollar bill or each type of coin as shown in the following table: Type of Cash Input Character Value (dollar) $1 Bill '$' 1.00 Quarter 'Q' 0.25 Dime 'D' 0.10 Nickel 'N' 0.05 Penny 'P' 0.01 Other Input Characters: 0.00 Only the five characters: '$', 'Q', 'D', 'N' and 'P' are considered as valid inputs. The function convert() should be able to return the corresponding value of the bill or coin to the main function. If the input character is NOT one of the valid characters listed above, the function convert() must return 0.00 2.) In the main function: Create a C program that allows a user to enter a single character from keyboard by using the function: scanf(" %c", &cash); (notice a space in front of %c) which mimics a scenario of inserting cash into a vending machine. Call the function convert() in the main program to convert the input characters (entered by user) '$', 'Q', 'D', 'N' or 'P' into the values of 1.00, 0.25, 0.10, 0.05 or 0.01, respectively. The program should repeatedly display the remaining balance and ask the user to enter a single character as long as there is still a remaining balance. When the remaining balance reaches 0.00 or once the value of cash inserted is greater than the remaining balance, the program should terminate and conclude the amount of change in dollar. Display the remaining balance and the change with 2 decimal places. Hint: Use double precision for the variable: balance Include additional libraries if needed. An example of input/output dialog is shown below: Remaining Balance is $1.50 Insert Cash: $ Remaining Balance is $0.50 Insert Cash: Q Remaining Balance is $0.25 Insert Cash: z Remaining Balance is $0.25 Insert Cash: D Remaining Balance is $0.15 Insert Cash: D Remaining Balance is $0.05 Insert Cash: N Here is your drink! and $0.00 change OR Remaining Balance is $1.50 Insert Cash: P Remaining Balance is $1.49 Insert Cash: Q Remaining Balance is $1.24 Insert Cash: $ Remaining Balance is $0.24 Insert Cash: $ Here is your drink! and $0.76 change Upload your source code (.c file) below: (only .c file will be graded!)
