The course teaches the basic techniques of computer programming and the basic knowledge of computer structure, and uses the elective programming language to learn how to solve given engineering problems in numerical value interpretation method and structural programming method. Based on the elective programming language, data structure, arrangement, pointer, method of use for auxiliary program are learned, and, uses the concept of systematic division of problem solving and the concept of module to make the algorithm analysis and program practice of problems on the numerical value field and non-numerical value field.
