Explain the concept of structural complexity.

Structural complexity refers to the level of complexity within a program's structure or design. It focuses on the organization and arrangement of program components, such as modules, functions, and classes, and how they interact with each other.

The concept of structural complexity is concerned with the overall complexity of a program's architecture and the relationships between its components. It considers factors such as the number of components, the complexity of their interactions, and the overall organization of the program.

Structural complexity analysis helps in understanding the overall complexity of a program and identifying potential areas of improvement. It allows developers to assess the maintainability, readability, and scalability of a program's structure, which can impact its overall performance and ease of development.

By analyzing the structural complexity of a program, developers can identify potential bottlenecks, dependencies, and areas of code that may be difficult to understand or modify. This analysis can help in making informed decisions about refactoring, optimizing, or redesigning the program's structure to improve its overall quality and maintainability.
