C语言自带一些数据类型,包括char,int,double,指针,union和struct。 char,int表示一定范围的整数值,但它表现行为确极大程度依赖硬件实现,比如在32位和64位机器,int的范围却是不一样的;其次double代表小数,但它表现的行为确和数学中的实数不一样,类似以下情况: doublenum=0.1+0.1+0.1;// 输出结果为 0.300000000000000...

The client-side object cache is allocated in the program's process space. This object cache is the memory for objects that have been retrieved from the database server and are available to your application. If you initialize the OCCI environment in object mode, your application allocates memory...
In the programmer’s world, this is the program-in-the-large or, grossly, the form of the system data. The part of MVC that helps people understand the whole of the data forms necessary to a given set of related tasks speaks largely to the right brain. The brain takes in the screen...
