The library is a test library. It may not as efficient and safe as C++ standard library.

This is not for production systems. Please use std::string instead.

该库文件仅供测试使用。此库有可能无法达到C++标准库的效率与安全性。

它不是为生产系统设计的。请使用std::string替代它。

如果需要使用该库（强烈不推荐），首先执行

If you want to use this library (strongly not recommand), please execute the following command first

make string.o

随后在编译项目的时候，增加本库include与lib的位置参数。

Then please add the params to specify include and lib directory of the library when you compile your project.

如果仅需查看该库的运行效果，请执行

If you only need to evaluate the library, please execute the following command

make all

该指令会生成test_default与test_origin两个可执行文件，分别使用该库与C++标准库。

The command will generate two executable named test_default and test_origin, which uses this library and C++ standard library.
