In this tutorial, we will learn about strdup string function in C programming language
strdub() – In C programming language, strdup string function is a predefined string function which is used to duplicate given string.
Syntax for strdub() function is given below:

printf("This is duplicate the string of:%s",strdup(p));
getch();
return 0;
}
When above program me is compiled it will produce the following result
This is duplicates the string of :John seela
