写一个函数，求一个字符串的长度，在main函数中输入字符串，并输出其长度-Writing a function, and the length of a string, in the main function in the input string and output its length

HTML是网页主要的组成部分，基本上一个网页都是由HTML语言组成的，所以要学习网站怎样建设，必须从网页的基本语言学起。-HTML is an integral part of the main page, is basically a Web page is composed by the HTML language, so to learn how to build web site must be from the web site from the basic linguistics.

汇编语言二进制转换为十六进制模块，代码正确。。。。希望有用-Assembly language is converted to hexadecimal binary module, the code correctly. . . . Want to be useful

此程序为KEIL环境下开发的代码（开发环境备选里没有KEIL），功能在成功运行后可以播放“生日快乐”歌。所需要的开发硬件为AT89C51为主芯片的单片机。-This program is developed under the code in KEIL environment (development environment, where there is no alternative KEIL), features a successful running play " Happy Birthday" song. Required the development of hardware-based chip microcontroller AT89C51.
