std::strpbrk - cppreference.com

const char* strpbrk( const char* dest, const char* breakset );

Â 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.

[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

#include <cstring>
#include <iomanip>
#include <iostream>
 
int main()
{
    const char* str = "hello world, friend of mine!";
    const char* sep = " ,!";
 
    unsigned int cnt = 0;
    do
    {
        str = std::strpbrk(str, sep); // find separator
        std::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
