---- Need help with STRINGS.

[DaniDak]

Hi,

Can anyone show me how to copy multiple multi-word strings from a linked-list to a dynamiclly sized string array.
I allready have a linked-list with multi-word strings in it, I need to create an array of strings of the exact size needed (dynamically allocated using new), copy the strings to the array from the linked-list.

I know that their is two ways to do it.
1. copy string into a char*[]
2. copy string into a string[]
after I have copied the strings into the array I need to be able to sort and search the array.

thank you

The function you want is
strcpy( char *, const char *)
(found in string.h) which copies the chars of the second arguement into the first arguement.

When allocating space for the copy, you can use function
strlen( const char * )
to get the size of a string minus the terminating null character, which sets you up to allocate memory like this:
char * whatever = new char[ strlen( aString ) + 1 ];
then use
strcpy( whatever, aString );
for the copy.

you can do it in a loop ..
something similar to this {strcat will do}


#define MAX 200

int main (int argc, char *argv[]) {
int j;
char *buff;
buff = (char*)malloc(MAX);

memset (buff, '\0',sizeof(buff));
for (j=1; j<argc; j++) strcat (buff,argv[j]);

return 0;
}

oops .. NEW not malloc
