You are asked to write a C program that will accept representing the number of dollars and cents to give to a customer in their change by allowing the user to enter the amount of change as dollars and cents as a double (real number). The program should calculate the minimum amount of coins used of each denomination and display this to the user. Valid dollar values are 100, 50, 20, 10, 5, 2 and 1 and valid coin values are 50, 20, 10 and 5. Your solution (program and algorithm) should be modular in nature and should output the correct combination of dollar and cent denominations required and should be able to work for any valid dollar amounts. Cents amounts should be in multiples of 5 Note that for this problem the principle of code reuse is particularly important and a significant number of marks are allocated to this. You should attempt to design your solution such that it consists of a relatively small number of functions that are as general in design as possible and you should have one function in particular that can be reused (called repeatedly) in order to solve the majority of the problem.
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.
