我们可以有多少级指针?
单个变量中允许有多少个指针(*)?
How many pointers (*) are allowed in a single variable?
让我们考虑以下示例.
int a = 10;
int *p = &a;
同样我们可以有
int **q = &p;
int ***r = &q;
等等.
例如
int ****************zz;
推荐答案
C标准规定了下限:
276 实现应能够翻译和执行至少一个程序，该程序包含以下每一项限制的至少一个实例:[...]
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 个指针、数组和函数声明符(任意组合)修改声明中的算术、结构、联合或 void 类型
279 — 12 pointer, array, and function declarators (in any combinations) modifying an arithmetic, structure, union, or void type in a declaration
上限是特定于实现的.
