strpbrk in C language

The strpbrk function is one of the String Function, which is used to find the first character in a first string that matches any character in a second string. In this article we will show you, How to use strpbrk in C Programming language with example.

C strpbrk syntax

The basic syntax of the strpbrk in C Programming language is as shown below.

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

or we can simply write it as:

strpbrk(str1, str2);

TIP: You have to include the #include<string.h> header before using this strpbrk string function.

strpbrk in C language Example

This program will help you to understand the strpbrk with multiple examples.

/* C strpbrk Function example  */

#include <stdio.h> 
#include<string.h>
 
int main()
{
   	char str1[50] = "abcdcefgdhiejk";
   	char str2[50] = "ce";
   	char *result;
	
   	result = strpbrk(str1, str2);
   	
   	if(result)
   	{
   		printf("\n The First Matching Character = %c", *result);	
	}
	else
	{
		printf("\n We haven't found the Character");	
	}
}

OUTPUT

strpbrk in C Example 2

Instead of predefined the two strings, this program allows the user to enter string 1, and string 2. Next, it will find first records from string 1 that matches with any character in string 2

/* C strpbrk Function example  */

#include <stdio.h> 
#include<string.h>
 
int main()
{
   	char str1[50], str2[50];
   	char *result;
	
	printf("\n Please Enter any String  : ");
	gets(str1);	
	
	printf("\n Please Enter the String that you want to Match : ");
	gets(str2);	
	
   	result = strpbrk(str1, str2);
   	
   	if(result)
   	{
   		printf("\n The First Matching Character = %c", *result);	
	}
	else
	{
		printf("\n We haven't found the Character");	
	}
}

OUTPUT

Although all the four characters in dyle string exists in str1, It returned the output as l. This is because, l is the first occurrence letter in string 1 compared to e y d
