C++ typedef syntax rules

Question

For the life of me I cannot find a good explanation of what are the rules that are used to convert a typedef to a C++ statement. The simple cases I understand. But consider this from Danny Kalev:

typedef char * pstr;
int mystrcmp(const pstr, const pstr); //wrong!

Danny Kalev then writes:

The sequence const pstr actually means char * const (a const pointer to char); not const char * (a pointer to const char.

I cannot find anywhere the rule to explain why "const pstr" would be converted to "char * const".

Thanks for any help.

Answer 1

It's because pstr is an alias for char* and when you do const pstr is a bit like saying const (char*) and not (const char)*.
