whats a better way to do this

Code:

char dontneed[20];
char need[20];
char astring[40];

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

i dont need dontneed[], just need[]...whats better?

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:

Code:

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

Maybe?

Code:

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...
