(C++) Need major help in soda machine code. It must follow the diagram exactly no more no less. (Crucial) If user puts in money and then decides to return, code must give back money. (I couldnt get this part) . Their are two drink options and each cost 0.75$. If possible, make options to enter like a real machine. Quarters, $1,$5, or just simply type in money. Thank you. (4 circles in diagram crucial, no more no less) Please.
