c++ - C/C++: `const` position in function's argument list

Question

void func1 (const int *);
void func2 (int const *);
void func3 (int * const);

Which two signatures are equivalent? If none of them are, can you please explain the subtle differences?

Answer 1

前两个是等价的（int 是 const），第三个是 const 的指针（即参数本身）。
