(C++11)(C++11)
Defined in header
<cwchar>
const wchar_t* wcspbrk( const wchar_t* dest, const wchar_t* src );
wchar_t* wcspbrk( wchar_t* dest, const wchar_t* src );
Finds the first character in wide string pointed to by dest, that is also in wide string pointed to by src.
Contents
[edit] Parameters
dest
-
pointer to the null-terminated wide string to be analyzed
src
-
pointer to the null-terminated wide string that contains the characters to search for
[edit] Return value
Pointer to the first character in dest, that is also in src, or a null pointer if no such character exists.
[edit] Notes
The name stands for "wide character string pointer break", because it returns a pointer to the first of the separator ("break") characters.
[edit] Example
Run this code
#include <cwchar> #include <iomanip> #include <iostream> int main() { const wchar_t* str = L"Hello world, friend of mine!"; const wchar_t* sep = L" ,!"; unsigned int cnt = 0; do { str = std::wcspbrk(str, sep); // find separator std::wcout << std::quoted (str) << L'\n'; if (str) str += std::wcsspn (str, sep); // skip separator ++cnt; // increment word count } while (str && *str); std::wcout << L"There are " << cnt << L" words\n"; }
Output:
" world, friend of mine!" ", friend of mine!" " of mine!" " mine!" "!" There are 5 words
