Level II C preparation -- basic concepts of program design

The concept of procedure ：

A program is a collection of instructions

Instructions --- compile --- The computer runs

Instructions ： Written execution program （ Steps to do ）

compile ： Convert a program to binary

The computer runs ： Run the binary to the result

C The running process of the program ：

Source program （.c or .cpp）--- Target file （.obj）--- Executable file （.exe）

The steps of programming ：

1, Determine the data structure

2, Determine the algorithm ： Algorithm 5 Big characteristic

Fineness （ Limited steps ）, deterministic （ The meaning is certain ）, The feasibility of （ Can achieve ）, Yes 0 One or more inputs , Yes 1 One or more outputs

3, code

4, Debug the program on the computer

5, Organize and write documents

Structured programs ：

Three structures ： Sequential structure , Selection structure , Loop structure
