In what situation would you use a flowchart?

Using a flowchart is particularly effective for visualizing the steps in an algorithm. Flowcharts provide a clear and graphical representation of the processes or decisions that need to take place in order to accomplish a task or solve a problem. Each shape in a flowchart represents a specific type of action or node in the process, making it easy to follow the workflow from start to finish.

This visualization helps programmers and stakeholders understand the logical flow of the algorithm without needing to delve into the actual code. It can simplify complex processes, making it easier to identify potential issues, and is useful for documenting and communicating ideas.

In contrast, determining the speed of code execution, inputting data into a program, or defining complex variables are tasks that aren't primarily focused on outlining procedural steps and do not benefit from the graphical representation that flowcharts provide. Therefore, using a flowchart is most appropriate when illustrating the sequence of steps involved in an algorithm.
