What is the primary purpose of a flow chart?

A flow chart is primarily used to visually display the sequence of activities in a process. By providing a graphical representation, it enables individuals to outline each step systematically, making complex processes easier to understand and follow. This visual approach helps in identifying potential issues, streamlining procedures, and communicating the flow of operations clearly to others who may need to be involved in the process.

The use of symbols such as arrows, ovals, and rectangles in a flow chart helps to illustrate different types of actions or decisions. This can significantly enhance collaboration and efficiency, as stakeholders can quickly grasp the overall structure and workflow without needing to read through detailed documentation.

The other options relate to functions that flow charts do not perform. Writing code involves the implementation of algorithms in programming languages, performing calculations is focused on numerical operations, and debugging a program pertains to identifying and resolving errors in code execution. Each of these tasks requires different tools and methodologies that are separate from the primary function of a flow chart.
