指针数组是一组有序的指针的集合。指向指针的指针运用的好处：避免重复分配内存；只需要进行一处修改；代码的灵活性和安全性都显著提高Pointer array: An array whose element value is a pointer is a pointer array. A pointer array is an ordered collection of pointers.Advantages of using pointers to pointer...
*---①pointer operator (指针运算符)( dereference): to declare that the variable after it is a unsign-int-type variable which stores the address of another variable ②indirection operator (间接访问运算符) : to access the value of the variable that the pointer is pointing to 单目运算符"*"必...

c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///< 2个参数printf("%d, %d", a, b);///< 3个参数 测...

Access to a data source through aCRecordsetobject is always shared. Unlike theCDaoRecordsetclass, you cannot use aCRecordsetobject to open a data source with exclusive access. When you callOpen, a query, usually a SQLSELECTstatement, selects records based on criteria shown in the following table...

of a pointer is an address, and this p is a pointer variable, while we define i as a value, not an address. 对于P=&i，&操作符就表示取变量的地址，就如这里的&i指的就是变量i的地址。操作符*表示对指针做解引用操作，怎么理解它呢，就还是上面的程序，p=&i，这里p保存了i的地址，...
