Structured programming 1.1 Structured programming principle It uses a subroutine, code blocks ( English: block structures ), for cycle and while cycle structure, to replace the traditional goto. Hoping to improve computer program clarity, quality and development time, and avoid to write spaghetti code. 1.2 Structured programming features Structured programming must be the function of the system of rational analysis, decomposition and synthesis, so the related personnel requirements higher, in addition, when using a structured programming method, the need for data management. 1.3 Structured programming Structured programming structured programming theory as theoretical basis, structured programming theory mentions the use of sequential, selection and repeat the three assembly programming way, can be said that all computable functions. The three structure is sufficient to express CPU instruction cycle, can also mean that the Turing machine operation, this point of view, the processor executes the instruction can be seen as a structured programming, although the program may not be
