strcpy() manipulation function is used copy the characters of one string to another.

    char * strcpy ( char * destination, const char * source );

Using the above syntax, copying of characters from "source" to "destination" string can be done.

   #include <stdio.h>
   #include <cstring.h>
  
   int main ()
     {
        char astr []="Source string";
        char bstr [20];
        strcpy (bstr,astr);
        printf ("The content copied from astr 
                       to bstr is: %s\n", bstr);
        return 0;
     }

    The content copied from astr to bstr is: Source string

In the above example, this manipulation function is used to copy the characters of "astr" to "bstr".
