Listing 4 of 4 questions
Jennifer is writing a computer program for her A Level homework. Jennifer uses a program library to help her write her computer program. Describe how a program library can be used while writing a computer program. Jennifer uses an Integrated Development Environment (IDE) to write her computer program. The IDE allows Jennifer to use both an interpreter and a compiler while creating her computer program. Describe the ways in which Jennifer can use both a compiler and an interpreter while developing the program. Identify two debugging tools that a typical IDE can provide.

A software developer is working in a team writing a program for a client. The developer is writing a new program library to be used by the other team members. Define the term program library. Explain two benefits to the developer of choosing to create a Dynamic Link Library (DLL). The development team needs to use a translator whilst writing the program for the client. Identify whether an interpreter or a compiler would be more appropriate at this stage of the program development. Justify your choice. Translator Justification The development team uses an Integrated Development Environment (IDE). Complete the table by describing the typical features found in an IDE. Feature Description Breakpoints Dynamic syntax checks Context‑sensitive prompts Single stepping One section of the program being developed will convert user’s speech into commands. Explain how Artificial Intelligence (Acan be used in this program.

A programmer is developing a computer game in a high-level language to sell to the public. The programmer uses both an interpreter and a compiler at different stages of the development of the program. Explain the reasons why the programmer uses an interpreter while writing the program code. Explain the reasons why the programmer uses a compiler when the program has been written. The programmer needs to publish the game under a software licence so that it can be sold to the public. Identify the most appropriate type of software licence for the game and justify your choice.
