How does pseudocode aid in structuring a program?

Pseudocode is a high-level description of a computer program's functionality that focuses on the logic and structure rather than specific syntax dictated by programming languages. By using pseudocode, programmers can articulate the steps and flow of logic in an understandable way for both developers and non-developers.

It allows for clear representation of algorithms without getting bogged down by the intricacies and rules of a particular programming language's syntax. This abstraction helps in visualizing the program's structure, making it easier to identify logical errors, plan the implementation, and communicate ideas effectively within a team or with stakeholders.

The other options do not accurately reflect the purpose and function of pseudocode. For instance, it does not limit the use of variables or eliminate steps, nor does it provide execution of code, as pseudocode is not executable in the way actual programming code is. It serves primarily as a tool for planning and conceptualization, which enhances the overall programming process.
