程序设计 什么是程序设计 From Wikipedia,2020 Computer programming is the process of designing and building an executable computer program to accomplish a specific computing result or to perform a specific task.Programming involves tasks such as:analysis,generating algorithms,profiling algorithms'accuracy and resource consumption,and the implementation of algorithms in a chosen programming language. The purpose of programming is to find a sequence of instructions that will automate the performance of a task(which can be as complex as an operating system)on a computer,often for solving a given problem.Proficient programming thus often requires expertise in several different subjects,including knowledge of the application domain,specialized algorithms,and formal logic. 口程序设计：理解和分析问题， 算法设计与分析，编程实现与调试 http://math.ecnu.edu.cn/~jypan
