[CODE] [NEWBIE] Search and replace function

Hi. I've just created a search and replace function, to be used with colours and
other things. When I compile the code I get no warnings or errors, but the
crashes as soon as the function is run. Here's the code...

void search_replace(char *string, const char *find, const char *replace)
        char final[MAX_INPUT_LENGTH];
        size_t start, end, i;

        while (strstr(string, find) != NULL) {

                start = strstr(string, find) - string;
                end = start + strlen(find);

                for (i = 0; i < start; i++)
                        final[i] = string[i];

                strcat(final, replace);

                for (i = end; i < strlen(string); i++)
                        final[i] = string[i];

                sprintf(string, final);

It is supposed to take three arguments -  a string to be searched, the
string it's
searching for, and what to put in place of that. Then for every occurance of
it puts in replace. Any help would be appreciated. Thanks,
