常量指针(pointer to constant)和指针常量(constant pointer) 一个指针可以操作两个实体,一个是指针值(即地址),一个是间访值(即指向的实体)。于是指针的常量性也分为两种:常量指针(pointer to constant)和指针常量(constant pointer)。 指针常量是相对于指针变量而言的,也就是指针值不能修改的指针。常量指针是指向...

The variableyin these declarations is declared as a constant pointer to anintvalue. The value it points to can be modified, but the pointer itself must always point to the same location: the address offixed_object. Similarly,zis a constant pointer, but it's also declared to point to anint...
LLVM的设计目标是提供灵活、可扩展和高性能的编译器技术,它可以用于各种编程语言和平台。 在LLVM中,PointerType是一种数据类型,用于表示指针类型。常量指针(Constant Pointer)是指指针所指向的内存地址是不可修改的。这意味着通过常量指针无法修改指针所指向的数据,但可以修改指针本身。 常量指针的主要优势是提供了更强...
