The 2nd chapter the Soul of algorithm----program

2.0 Four aspects of program design

1. Data structure (description, Main, processing object ) 2. Algorithm (description of operation, Main, soul ) 3. Programming method ( appropriate method for programming required ) 4. Language Tools ( tools )

2.1 What is an algorithm

1. Algorithm: Methods and steps to solve a problem (generalized)

2. Computer algorithm: 1. Numerical algorithm (1. Objective: To find the numerical solution; 2. The research of this algorithm is more in-depth, often has a ready-made model, can be used in numerical analysis method) 2. Non-numeric arithmetic (only some typical non-numerical arithmetic, such as sorting algorithm, searching search algorithm, etc., there are ready, Mature algorithms can provide)
