On this page we will see the series of Portugal Euro Coins, composed of 8 divisional coins, three “red”, three “yellow” and two bimetallic coins.

Coins Online Auction: How does it work?.subsequent decompositions of each step (i.e. Your solution (algorithm and program) should be designed using a modular approach. A correct solution would give a 20 cent coin and a 10 cent coin.Īfter each output, the user should be asked whether they wish to continue (i.e., enter another amount) or exit/terminate the program. For example, a poor solution for an input of 30 cents would give six 5 cent coins. The solution should aim to give as much of the higher valued coins as possible. Your program should then return the minimum number of coins (in the selected currency) that sum up into that number. If the chosen currency is AU$, your program should ensure that the input value is a multiples of 5. It should then ask the user to input an amount of money in cents as a number between 1 to 95 inclusive.

(Note that these coins are randomly chosen just for the purpose of this exercise and may not correspond to the actual reality.)

The program should work as follows First, it will ask the user to select a currency among the following three:ġ) US$, which has four types of coins: 50, 25, 10 and 1 centsĢ) AU$, which has four types of coins: 50, 20, 10 and 5 centsģ) Euro, which has four types of coins: 20, 10, 5 and 1 cents The amount of money entered in is in cents and should be an integer value in the range of 1 to 95 inclusive. You are asked to write a modular solution (algorithm and C program) that will accept as input an amount of money (in cents) in a certain currency and return the optimal number of coins in that currency.
