Write a program that inputs the length of two pieces of wood in yards and feet (as whole numbers) and prints the total.

Hint: Change all of the inputs into feet first - remember there are 3 feet in each yard. Now that the wood is in feet, find the yards and feet similarly to the last practice, using regular and modular division.

Without input validation, a user might take advantage of applications like setuid executables or web applications like CGIs to make them act badly by feeding them different kinds of data.

Format string vulnerabilities may be caused by this kind of issue. Any harmful action against a computer system that involves manually putting odd data into a typical user input field is known as an input validation attack. The user may see client-side validation in action. It entails using JavaScript for input form validation. A JavaScript validator, for instance, would provide an error if anything was submitted that did not conform to a phone number or email if the input was submitted for a phone number or email.

Single sign-on; Multi-factor authentication is the type of authentication have you implemented.

What is an authentication?

Authentication is the act of proving an assertion, such as a computer system user's identification. Authentication is the method of verifying a person's or thing's identity, as opposed to identification, which is the act of indicating that identity. It could entail validating personal identification documents, verifying the authenticity of a website with a digital certificate, carbon dating an artefact, or guaranteeing that a product or document is not counterfeit. Authentication is important in a variety of industries. A recurring difficulty in art, antiques, and anthropology is proving that a certain artefact was created by a specific individual or in a specific area or period of history. Verifying a user's identity is frequently required in computer science to give access to secret data or systems.
