Perhaps you can use strtok() to skip to the second substring. It also looks (from reading the sscanf manpage) that you can use the format string '%*' to suppress assigning the matched portion to anything. Not having tried it, this is a guess:

sscanf(astring, "%* %s", need);

sscanf(astring , "%s %s",  need,  need);
then the second need overwrites the first?

strcpy(need, strchr(astring, ' ')+1);

Assuming you can always trust the input to have a space that is...
