Strings.....

Please understand that this is the list for help on the GNU C

anybody on this list to implement this function for you. Please use

If you really meant to write this, you need to study C in more detail.
When you assign "Hello\0" to string, than the result of the earlier
allocation is lost and garbage. Also, modifying the string won't work
because it is a constant.

To copy overlapping memory, you can use the memmove(3) function.
