Pearl, Python, Lula, and Java are all examples of what?

• A. Languages
• B. Frameworks
• C. Tools
• D. Libraries

Answer: (A)

Programming languages are formal systems for instructing a computer. Perl, Python, Lua, and Java are examples because each provides its own syntax and rules for expressing computations, data handling, and control flow. They let you write code in their distinct styles, which is then executed by a compiler or interpreter according to that language’s rules. They differ in syntax and typical use cases, but all share the ability to tell a computer what to do. They are not frameworks, which supply structure and reusable components on top of a language; not libraries, which are collections of prewritten code you call from your program; and not tools, which are utilities used to develop, test, or run code. Note: the first item is typically Perl, not Pearl.
