NAME¶

std::strpbrk - std::strpbrk

Synopsis¶

Defined in header <cstring>
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.

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

Return value¶

Pointer to the first character in dest, that is also in breakset, or null pointer if
no such character exists.

Notes¶

The name stands for "string pointer break", because it returns a pointer to the
first of the separator ("break") characters.

Example¶

// Run this code

#include <iostream>
#include <cstring>
#include <iomanip>

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
