How many pointers (*
) are allowed in a single variable?
Let's consider the following example.
int a = 10;
int *p = &a;
Similarly we can have
int **q = &p;
int ***r = &q;
and so on.
For example,
int ****************zz;
The C
standard specifies the lower limit:
5.2.4.1 Translation limits
276 The implementation shall be able to translate and execute at least one program that contains at least one instance of every one of the following limits: [...]
279 — 12 pointer, array, and function declarators (in any combinations) modifying an arithmetic, structure, union, or void type in a declaration
The upper limit is implementation specific.
