说明：  本软件一共收录了355个TC2.0库函数，每一个函数都提供了相应的头文件，函数用途，函数全称，输入输出参数，函数的返回值，以及函数是如果应用的例子。提供了按功能分类，字母分类，直接输入，下拉列表等快速查询。是学习C语言，C＋＋语言的好助手。希望能给C，C＋＋编程爱好者一点帮助，学习好C语言。
(The software contains 355 WITH TC 2.0 libraries, each provide a function corresponding to the first document, the function uses the generic function, input and output parameters, function return values, and if the function is an example. The functional classification, in alphabetical classification, direct input, such as the drop-down list to quickly find. Learning C, C++ Language good assistant. In hopes of giving the C and C++ programming enthusiasts bit of help, studying C language.)
