string manipulation

[Chad Gibbons]

        For several applications it would become necessary to remove a small
string from a larger one. There appears to be an easy way to do this, and here
is a sample piece of code I was testing :

    char *squeeze(cs, ct)
        const char cs[];
        const char ct[];
    {
        register int i;
        int j,x;

        j = strcspn(cs, ct);
        for (i = j; cs[i] != '\0'; i++)
            cs[i] = cs[i + x];
        return (char *)s;
    }
It seems the algorithm should work. However, if nothing else is wrong, one
basically major thing is: you cannot over step the array bounds. If you do,
you get a nifty little core dump error. So, I'm looking for a good way to do
this. I tried it with pointers, but I had worse luck than with this. For all
I know there is some obscure library function to do this, but I didn't find
one in our library. Any one have a better way to do it? Post it, inform us
all. I'm curious to see if this can be done with explicit pointers and not
just with array indexes.
