string to char

I. Possible combinations: (1) const char * P (2) Char const * P (3) char * const P(4) const char ** P (5) Char const ** P (6) char * const * P (7) Char ** const P Of course, there are several cases of inserting a const in (5), (6), and

Programming has been a headache recently. This type of conversion can be done by knowing that it can be switched, but it is always hard to remember. I will keep searching through the Internet and summarize it here. For future convenience, of course,

About wchar_t In the C ++ standard, wchar_t is a wide character type. Each wchar_t type occupies 2 bytes and has a 16-bit width. Wchar_t is required for the representation of Chinese characters. Char, we all know, occupies a byte, 8-bit width.

Constraints for assigning values according to ansi c: 1. Both operands are pointers to compatible types with or without delimiters. 2. the type pointed to by the Left pointer must have all the qualifiers of the type pointed to by the right

1 The nature of the array An array is a collection of multiple elements that are distributed in memory in an address-connected cell, so that you can access elements of different cells by its subscript. 2 pointers. A pointer is also a
