php$a;$b=0;$c=array();$d='';$e=null;empty,用了会上瘾这是一个用了会上瘾的语言结构!多好,empty可接受的参数是一个变量,任意类型,哪怕是变量不存在,只要变量被boolean转换之后是false(参考:php的boolean都有哪些),那么empty返回的就是false,并且不会出现警告!等价于不过注意的是,empty里面不能使用表达...
OCIDefineArrayOfStruct 函数功能:以数组方式进行列绑定。 函数原型: sword OCIDefineArrayOfStruct ( OCIDefine *defnp, OCIError *errhp, ub4 pvskip, ub4 indskip, ub4 rlskip, ub4 rcskip ); 函数参数: 参数描述 defnp (IN)绑定结构指针。

typedef int INT; typedef int ARRAY[10]; typedef (int*) pINT; typedef可以增强程序的可读性,以及标识符的灵活性,但它也有“非直观性”等缺点。 二、#define的用法 #define为一宏定义语句,通常用它来定义常量(包括无参量与带参量),以及用来实现那些“表面似和善、背后一长串”的宏,它本身并...

3. R..的回答 The reason is that most of the time, you want a constant, not a const-qualified variable. The two are not remotely the same in the C language. For example, variables are not valid as part of initializers for static-storage-duration objects, as non-vla array dimensions (...
