指针类型(Pointer Types):用于存储内存地址。 数组类型(Array Types):用于存储固定大小和类型相同的元素序列。 结构体类型(Struct Types):用于组合不同类型的数据。 联合体类型(Union Types):用于存储不同类型的数据,但在任何时候只能存储其中一种类型。 函数类型(Function Types):代表函数的返回类型和参数。 4. 头...

When declaring pointer data or a function that returns a pointer type, the preferred use of*is adjacent to the data name or function name and not adjacent to the type name. Examples: char*linux_banner;unsignedlonglongmemparse(char*ptr,char**retptr);char*match_strdup(substring_t*s); ...
The form int ar[] also means that ar is type pointer-to- int, but only when used to declare formal parameters. The idea is that the second form reminds the reader that not only does ar point to an int, it points to an int that’s an element of an array.”第六版的翻译是 "int...
The keyword void has three uses: to specify a function return type, to specify an argument-type list for a function that takes no arguments, and to specify a pointer to an unspecified type. You can use the void type to declare functions that return no value or to declare a pointer to ...
主要是看下吧里对const是怎么讨论的,结果度娘不让看……1.在<The C++ Programming Language>中,关于指针和常量有这么两段描述:To declare a pointer itself, rather than the object pointed to, to be a constant, we use the declarator operator *const instead of plain *.The declarator operator that ...
