Answer:

Laws are in place to cover your creative work, which includes code you have written.

Explanation:

Copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.

A copyright can be defined as an exclusive legal right granted to the owner of a creative work (intellectual property) to perform, print, record, and publish his or her work. Also, the owner is granted the sole right to authorize any other person to use the creative work.

For instance, copyright law which protects the sharing and downloading rights of music is known as the Digital Millennium Copyright Act (DMCA).

An intellectual property can be defined as an intangible and innovative creation of the mind that solely depends on human intellect.

Simply stated, an intellectual property is an intangible creation of the human mind, ideas, thoughts or intelligence. They include intellectual and artistic creations such as name, symbol, literary work, songs, graphic design, computer codes, inventions, etc.

Hence, laws are in place to cover a person's creative work, and it includes code he or she have written.
