Editing Pointer (computer programming) (section)

====Pointer declaration syntax overview====
These pointer declarations cover most variants of pointer declarations. Of course it is possible to have triple pointers, but the main principles behind a triple pointer already exist in a double pointer. The naming used here is what the expression <code>typeid(type).name()</code> equals for each of these types when using [[g++]] or [[clang]].<ref>{{cite web|url=https://linux.die.net/man/1/c++filt|title=c++filt(1) - Linux man page}}</ref><ref>{{cite web|url=http://refspecs.linux-foundation.org/cxxabi-1.83.html#mangling|title=Itanium C++ ABI}}</ref>

<syntaxhighlight lang="C">

char *A5_Pc [5];       /* array of pointers to chars */

The following declarations involving pointers-to-member are valid only in C++:
<syntaxhighlight lang="Cpp">
class C;
class D;
char C::* M1Cc;              /* pointer-to-member to char */
char C::*A5_M1Cc [5];        /* array of pointers-to-member to char */
char* C::* M1CPc;            /* pointer-to-member to pointer to char(s) */
char C::** PM1Cc;            /* pointer to pointer-to-member to char */
char (*M1CA5_c) [5];         /* pointer-to-member to array(s) of chars */
char C::* FM1CcvE();         /* function which returns a pointer-to-member to char */
char D::* C::* M1CM1Dc;      /* pointer-to-member to pointer-to-member to pointer to char(s) */
char C::* C::* M1CMS_c;      /* pointer-to-member to pointer-to-member to pointer to char(s) */
char (C::* FM1CA5_cvE())[5]; /* function which returns pointer-to-member to an array of chars */
char (C::* M1CFcvE)()        /* pointer-to-member-function which returns a char */
char (C::* A5_M1CFcvE[5])(); /* an array of pointers-to-member-functions which return a char */


</syntaxhighlight>
The <code>()</code> and <code>[]</code> have a higher priority than <code>*</code>.
