扩展资料:
代码就是程序员用开发工具所支持的语言写出来的源文件,是一组由字符、符号或信号码元以离散形式表示信息的明确的规则体系。代码设计的原则包括唯一确定性、标准化和通用性、可扩充性与稳定性、便于识别与记忆、力求短小与格式统一以及容易修改等。 源代码是代码的分支,某种意义上来说,源代码相当于代码。
现代程序语言中,源代码可以书籍或磁带形式出现,但最为常用格式是文本文件,这种典型格式的目的是为了编译出计算机程序。计算机源代码最终目的是将人类可读文本翻译成为计算机可执行的二进制指令,这种过程叫编译,它由通过编译器完成。
源代码(也称源程序),是指一系列人类可读的计算机语言指令。
源代码是相对目标代码和可执行代码而言的。 源代码就是用汇编语言和高级语言写出来的地代码。目标代码是指源代码经过编译程序产生的能被cpu直接识别二进制代码。可执行代码就是将目标代码连接后形成的可执行文件,当然也是二进制的。

slider,jq自己下载,相信不用我教。
顺便可以看看教程,对这些有点了解。
