The goal of modern programming is mainly to pursue a clear structure, strong readability, and easy division of labor and cooperation in writing and debugging.
Most modern procedural languages encourage structured programming. Structured programming mainly emphasizes the readability of the program. The specific situations are as follows:
Structured Programming typically uses a top-down design model, where developers map the entire program structure to a single small part. A defined function or a collection of similar functions is encoded in a single module or submodule, which means that the code can be loaded into memory more efficiently and the module can be reused in other programs. After the module is tested individually, it is integrated with other modules to form the entire program organization.
The program flow follows a simple hierarchical model, using loop structures such as "for", "repeat", and "while". The use of "Go To" statements is discouraged. Almost any language can use structured programming techniques to avoid the usual pitfalls of unstructured languages. Unstructured programming must rely on developers to avoid structural problems, resulting in poorly organized programs.
