What is pseudocode?

Pseudocode is indeed a set of instructions written in a non-programming language designed to describe an algorithm's process in a way that is easy to understand for humans. It combines natural language with programming constructs, allowing developers to plan and outline the logic of the program without getting bogged down by the syntax of specific programming languages. This makes it an effective tool for conceptualizing algorithms before actual coding begins.

By using pseudocode, programmers can focus on the logical flow and structure of their programs, facilitating easier communication and understanding among team members who may have varying levels of programming expertise. Pseudocode helps clarify the intended function of the program, making it a valuable step in the software design process.

The other options provided do not accurately describe pseudocode. For example, it is not a low-level programming language, nor is it a visual representation of programming logic. Additionally, pseudocode does not serve as a framework for developing APIs, as its purpose lies primarily in planning and outlining algorithms rather than in technical implementation.
