Question

i need help in c programming
i am trying to concatenate names together with a comma in between. anyone with any knowledge on that?

Answer 1

You need to allocate enough space for both the original strings+2. Then just copy from one, append the comma, and copy from the other.

Answer 2

you can make while loop to take the names
with counter if the counter in start don't print comma before the name, other print comma before the name.

Answer 3

If you include string.h, it has a strcat function and probably a strncat function take pointers to strings and concatenates them (or the size in arg3 of strncat) into the string given in arg1's space.
