标准程序库 标准程序有组织的集合。把经常用的计算过程与计算方法编成精度较高、运算速度较快而又尽可能短的典型程序，称为“标准程序”。
标准程序库含有一些目的档，而且是由LIB工具建立的。
Standard libraries contain objects and are created by the lib tool.
对标准程序库而言，有很多程序库函数在固定的对象中返回值，总是重复使用同一对象，这就使得那些函数不可重入。
As with the standard library, there can be many library functions that return values in fixed objects, always reusing the same objects, which causes the functions to be non-reentrant.
如果记得没错的话，Stroustroup在“C++的设计与演化”一书中说到他应该写一个标准程序库来支持多继承，我等无福消受啊。
If I recall it right, Stroustroup wrote in "The Design and Evolution of C++" that he delayed a standard library in favor of multiple inheritance. I would have enjoyed it more the other way.
