how we can concatenate more then two strings .
without using multiple strcat statement.
example
i have
char *a="program";
char *b="lang";
char *c= "clang";
so how can i add these strings without using two strcat.
if i use more then one strcat .
my execution times increases so how can i reduce it
thank u
sree
you cannot reduce execution time. You can however - write it with 1 line using sprintf
sprintf(resbuf, "%s%s%s",a,b,c);
Here there is a possibility of memory overrun, so I always use some snprintf equivalent
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

It's a bit of a laugh if you believe that somehow, despite the fact that you don't know how to code a string concatenate function, that you're going to (with a bit of help), write up something much more efficient than the standard library function.
If your execution time is increasing, perhaps your function could be in-lined, but that's up to your compiler to accept or reject.
If you'll step through your code, dollars to donuts, your code is wasting time mis-using the strcat function. When you step through your code, you'll see it.
