Anhydride 2-methylhexanoic pentanoic structure
Write a program that reads in two integers and determines and prints if the first is a
multiple of the second.
a) first the program using if statements
b) then the program using if/else statements
(iv) Write a function, computePrice that receives two parameters: the first one is a character variable
indicating the size of the pizza (S, M or L) and the second an integer variable indicating the number of
toppings on the pizza. It then computes the cost of the pizza and returns the cost as a floating point
number according to the rules:
• Small pizza = R50 + R5.50 per topping
• Medium pizza = R70 + R6.50 per topping
• Large pizza = R90 + R7.50 per topping
(iii) Write a function void rectangle(int w, int h) to print an open rectangle of asterisks (*). The parameters w and h are the width and the height of the rectangle, expressed in number of asterisks.
(ii) Write a void function that receives four int parameters: the first two by value and the last two by reference. Name the formal parameters n1, n2, sum and diff. The function should calculate the sum of the two parameters passed by value and then store the result in the first variable passed by reference. It should calculate the difference between the two parameters passed by value and then store the result in the second parameter passed by reference. When calculating the difference, subtract the larger value from the smaller value. Name the function calcSumAndDiff.
(i) Write a function that returns the cube of the integer passed to it. For example cube(2) will
return 8 and
cube(3) will return 27.
