From cppreference.com
Defined in header <cstring> | ||
constchar* strpbrk(constchar* dest, constchar* breakset ); | ||

[edit]Parameters
| 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 |
[edit]Return value
Pointer to the first character in dest, that is also in breakset, or null pointer if no such character exists.
[edit]Notes
The name stands for "string pointer break", because it returns a pointer to the first of the separator ("break") characters.
[edit]Example
Run this code
#include <cstring>#include <iomanip>#include <iostream> int main(){constchar* str ="hello world, friend of mine!";constchar* sep =" ,!"; unsignedint cnt =0;do{ str = std::strpbrk(str, sep);// find separatorstd::cout<<std::quoted(str)<<'\n';if(str) str +=std::strspn(str, sep);// skip separator++cnt;// increment word count}while(str &&*str); std::cout<<"There are "<< cnt <<" words\n";}
Output:
" world, friend of mine!" ", friend of mine!" " of mine!" " mine!" "!" There are 5 words
