From cppreference.com
< cpp‎ | string‎ | byte

Defined in header `<cstring>` |  |
const char* strpbrk( const char* dest, const char* str ); |  |
char* strpbrk( char* dest, const char* str ); |  |

Finds the first character in byte string pointed to by `dest`, that is also in byte string pointed to by `str`.

### [edit] Parameters

dest | - | pointer to the null-terminated byte string to be analyzed
str | - | 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 `str`, or NULL if no such character exists.

### [edit] Example

Run this code

    #include <cstdio>
    #include <cstring>

    int main()
    {
        char* input = "hello world friend of mine";
        char* space = " ";
        char* pos = input;
        int word_counter = 0;

        do {
            pos = std::strpbrk(pos, space);
            word_counter++;
            pos ? pos++ : pos;
            std::printf("%d\n", word_counter);
        } while (pos != NULL);
    };

Output:

    1
