the green light by the Driver and Vehicle Licensing Authority (DVLA) to be used in Ghana. Most of the cars on our roads today are accident cars imported from the western world. It is being debated that these imported cars contribute immensely to the high road accident cases in Ghana. The government has decided to charge 0.5 % tax on every car purchased from KTA. This will increase sales of KTA cars and arguably reduce road accidents in Ghana. You are to write a program. Your program should: a. Request for a username and password to be inputted. Your username and password should grant access to the program if they are correctly inputted. b. Your program should have a method that calculates and displays the tax on any car purchased. c. Your program should be able to perform “b” above at least 10 times. d. Assuming sales have now gone up and the government has scraped the tax incentive. A tax of 25% imposed on each car sale. Modify a portion of the code to reflect the new development. e. Explain how the Ghana Revenue Agency (GRA) can use your program to calculate tax on goods imported into the country

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.
