That depends on what you mean.
There is no standard type Char; I presume you mean char.
To copy the value of a char* object to another one, just assign it.
To copy a string, use strcpy() (but first make sure that the target
has enough room).
If you're copying character arrays that aren't strings, use memcpy()
(or memmove() if they might overlap).

We must do something. This is something. Therefore, we must do this.
