The phase of the software development life cycle (SDLC) that corresponds to the production and distribution of new software is called implementation. This phase involves deploying the software to users and making it operational.
After months of hard work, the big day has finally arrived, and new software will be produced and distributed. Which phase of the software development life cycle is this?

The program you described, which shows the same slides in the same order every time it is run, is an example of a sequence structure. In programming, a sequence refers to the linear execution of instructions or statements in the order they are written.

“Luke,” “Cynthia,” and “Omar” are examples of strings. In programming, a string is a sequence of characters, which can include letters, numbers, and symbols, typically enclosed in quotation marks.

A program that gives the player five chances to guess a number will need to use a loop. A loop allows the program to repeat a certain block of code (in this case, the guessing logic) until the player has used all their chances.

The option that is NOT a markup language is Python. Python is a high-level programming language used for general-purpose programming, while SQL, Cypher, and GraphQL are considered query languages that can interact with databases, but they are not traditional markup languages. Markup languages typically describe data structure (like HTML or XML).
A program will recommend a movie to the user based on the input that the user provides about their interests. This program is an example of which of these structures?

The program that recommends a movie based on the input provided by the user about their interests is an example of selection. Selection structures involve making decisions in the code based on certain conditions (e.g., if the user likes action movies, then recommend an action movie).
