30. In your own words, define what "boilerplate code" means
**Boilerplate code, are sections of code that are repeated in multiple places with little to no variation.**
**It refers to code sections repeated throughout a program or software. The term "boilerplate" comes from the printing world,** **describing the pre-cut metal plates used to print text repeatedly. In programming, boilerplate code serves a similar purpose,** **saving developers time and effort by providing pre-written code they can use in their programs.**
