The program and recursion of computer introduction language and algorithm: combination-abstraction-repetition-construct

1. Abstract computing object and function definition and construction method, the program is composed of abstract constructs.

2. Program: Constructed by a basic action instruction, a combination of several instructions or an execution sequence for the implementation of complex actions. The program actuator saves the underlying operation at development time.

3. Abstract process, combination and construction level of computer system. The procedure is constructed, and the combination and abstraction are the basic means of constructing the program.

4. Abstraction and Construction: Name the computed object, use the name in the construct, and replace the names with the computed objects in the calculation.

5. The definition of recursion: itself calls itself, the higher order calls the lower order, constructs the infinite computation step. is brought forward by the back and then calculated by the front and back.

6. Primitive Recursive functions
