In this example, we use the strdup() function to duplicate a string. Then, we use the printf() function to display the “original” and “duplicate” string pointers in the command console. To do this, we include the “stdio.h” and “string.h” headers in our code and define the t...
strdup() and strdndup() in C C - strdup() The function strdup() is used to duplicate a string. It returns a pointer to a null-terminated byte string. Syntax Here is the syntax of strdup() in C language, char *strdup(const char *string); Example Here is
