In this program, we will use strtok_r() function. This function is used to split the string and get words from a specified string based on a specified delimiter.

The strtok_r() works similar to the strtok() function. But strtok_r() is a re-entrant function.

Program:

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

// C program to split the string
// using strtok_r() function

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

int main()
{
    char str[32] = "www.includehelp.com";
    char* word;
    char delim[2] = ".";

    char* ptr = str;

    while ((word = strtok_r(ptr, delim, &ptr)))
        printf("%s\n", word);

    return 0;
}

Output:

www
includehelp
com

Explanation:

In the main() function, we created a string str initialized with "www.includehelp.com". Then we split the string based on dot (.) delimiter using strtok_r() function and printed the words on the console screen.
