C strpbrk() Function Definition

The strpbrk() function accepts two string parameters. And, search any character of the second string within the first string passed as an argument in the function and returns the character pointer to the calling function.

Syntax

char *strpbrk(const char *str1, const char *str2);

Parameters

• str1 - The string to be scanned.
• str2 - The string containing the set of characters to match.

C strpbrk() Example

In this program, we will search the first vowel within the string using the strpbrk() function.

The source code to demonstrate the strpbrk() function is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.

// C - strpbrk() Function With Example

#include <stdio.h>
#include <string.h>

int main()
{
    char* ptr;
    char str[] = "Learn programming on www.includehelp.com";
    char vowels[] = "aeiou";

    ptr = strpbrk(str, vowels);
    if (ptr != NULL)
        printf("First vowel is: '%c' in the string\n", ptr[0]);
    else
        printf("No any vowel found within the string.\n");

    return 0;
}

Output

First vowel is: 'e' in the string

Explanation

In the main() function, we used the strpbrk() function to search any vowel within the string and return the character pointer to the calling function. Then we printed the first vowel on the console screen.
