Final answer:
A flowchart is the graphical design used in structured programming to lay out algorithms in predefined boxes, providing a clear visual sequence of actions.
Step-by-step explanation:
The graphical design representation for structured programming that forces designers to place algorithms into predefined boxes is known as a flowchart. A flowchart is a visual representation where each step of the process is laid out in individual boxes that are connected with arrows to show the flow of information. These diagrams are structured to provide a clear sequence of actions that reflects the algorithm's logic. Different shapes and symbols can be used in flowcharts, each representing different types of actions or steps in a process.
Flowcharts are utilized in many scenarios where a step-by-step process needs to be followed. They are widely used in computer programming to plan out the logic before writing actual code. They also serve as a way for programmers to communicate algorithms with others or to help in debugging a process. In other fields, for example, business processes and operations management, flowcharts are used to document, analyze, and improve complex processes.
