fun with casting

Hello All,

I'm trying to do a simple c program that will squish together several char arrays to create one large char array.

I'd like to be able to take "abc" "defg" "hijk" and create "abcdefghijk".

Here's what I have so far:

void squishChars(char *final, char *array ){

int i;
for (i=0; array[i]; i++){
strcat(final, array[i]);
}

}

final is the resulting squished char array ( in my example "abcdefghijk" )
array is similar to the following
const char *letters[] = {
"abc",
"defg",
"hijk",
NULL
};

When I attempt to compile, these are the errors I'm getting:
warning: passing arg 2 of `strcat' makes pointer from integer without a cast
warning: passing arg 2 of `squishChars' from incompatible pointer type

Running causes major trouble... a Status Access Violation.

I realize I need to cast array[i] as a char array, but I'm not sure how to do it... any ideas?

Thanks in advance!

re: fun with casting

the destination for strcat() should be a char[] (not const) with sufficent room for the concatenated characters. e.g.
when run gives
xyzabcdefghijk
