constwchar_t* wcspbrk(constwchar_t* dest,constwchar_t* src); | ||
wchar_t* wcspbrk( wchar_t* dest,constwchar_t* src); | ||
Finds the first character in wide string pointed to bydest, that is also in wide string pointed to bysrc.
Contents |
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 |
Pointer to the first character indest, that is also insrc, or a null pointer if no such character exists.
The name stands for "wide character string pointer break", because it returns a pointer to the first of the separator ("break") characters.
#include <cwchar>#include <iomanip>#include <iostream> int main(){constwchar_t* str= L"Hello world, friend of mine!";constwchar_t* sep= L" ,!"; unsignedint cnt=0;do{ str= std::wcspbrk(str, sep);// find separatorstd::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
