const char* strpbrk( const char* dest, const char* breakset ); | ||
char* strpbrk( char* dest, const char* breakset ); |
Scans the null-terminated byte string pointed to by dest for any character from the null-terminated byte string pointed to by breakset, and returns a pointer to that character.
| dest | - | pointer to the null-terminated byte string to be analyzed |
| breakset | - | pointer to the null-terminated byte string that contains the characters to search for |
Pointer to the first character in dest, that is also in breakset, or null pointer if no such character exists.
The name stands for "string pointer break", because it returns a pointer to the first of the separator ("break") characters.

const char* str = "hello world, friend of mine!";
const char* sep = " ,!";
unsigned int cnt = 0;
do

str = std::strpbrk(str, sep); // find separator

}Output:
" world, friend of mine!" ", friend of mine!" " of mine!" " mine!" "!" There are 5 words
