Your program should tell the user the price of the item and then the user will enter the amount of money that they are paying (this simulates them actually inserting cash). If the money collected is less than the price, print an appropriate message (such as: "Insufficient funds, no sale!") and then the program should exit. If enough money is collected determine the amount to return to the customer. If the change due is not zero, tell the user how much change they will receive. Next print a message (such as "Thank you~ enjoy your drink!") and end the program normally (at the return 0 statement). Note, your program should be able to handle all amounts of money (not just multiples of dollars but also cents such as $1.25). Also you may assume that the user is only entering a number and not the $ (though the $ coul be part of your prompt). Hint: Check how to do floating point comparisons Program 2. Write a program to determine the drink size based on the letter the user enters. Print a message to the user giving the various drink size options and then prompt the user for the drink size. The user can enter an's' or 'S' for small, an 'm' or 'M' for medium, and an T or 'L' for large. Depending on which size the user requests, print a message such as: "You have ordered a (small, medium, large) drink." In addition to displaying the size ordered, also record a price multiplier. The price multiplier for a small is 1, for a medium is 2, and for a Jarge is 3. If the user does not enter a valid character, print an error message (such as "Error: Invalid drink size") and exit the program You should use nested if-then-else statements for this problem. After the nested if-then-else statements, print the value of the price multiplier to ensure that the correct value was recorded (the price multiplier will be used in program 4). Hint: use the logical OR expression in your comparisons. Program 3. Write a program that displays the various drinks your vending machine offers along with the option number for each drink. Beside each option include the price (you can set the cost for the small, the costs for medium should be 2 times the cost of the small and the cost of the large should be 3 times the cost of the small)
