Design and implement a C$++$ program that mimics the operations of a vending machine that dispenses four different types of snacks.$$

$[$STEP$1]$ This program uses a 'class' definition for vending machine $("$SnackMachine$"),$ and within it must implement four functions; one each for a choice of snack. $$The functions are only required to print a statement on screen saying that the snack is dispensed.

$[$STEP$2]$ Once you code down your class, next implement the main$()$ function. Your main function declares an object of type "SnackMachine", and uses this object to call various functions to dispense snacks. Use a while$(1)$ and switch$-$statement to present a menu of snacks, prompt the user to make a choice, and call the appropriate function.
