I was in the library's multimedia room to do my assignment, but all PCs don't have Visual Studio and other smiliar programs. So I wrtie the code on Notepad for the question:

Design a solution that will determine and display the fewest number of ringgit and coins in change of a purchase value. The customer may pay any amount for the purchase. The changes are in the form of 1 cent, 5 cents, 10 cents, 50 cents, RM1, RM5, RM10 and RM50.

The following is an example of the solution result.

Purchase : RM 23.63
Payment : RM 100.00
Change : RM 76.37

RM50 = 1
RM10 = 2
RM5 = 1
RM1 = 1
50 cents = 0
10 cents = 3
5 cents = 1
1 cents = 2

Does it look correct or not?

Looks right. Other than needing some `<< endl` and semicolons at the end our your output statements.

A check that payment is atleast purchase price would help. Also, it's usually considered good practice to intiialize your variables in the delcaration. did find one bug `FiveCents = Cent / 50;`, shpuld be `FiveCents = Cent / 5;`.

Here's your code with a couple of changes:

``````// Ringgit_Make_Change.cpp : Defines the entry point for the console application.
