#define len      20
#define slen      "20"
char *names[4];
for(i=0;i<4;i+=1){ names[i] = (char *)malloc(len+1); }
scanf("%" slen "s", names[0]);
printf("%s, %s, %s",names[0],names[1],names[2]);

Sure the same can be done with gets(names[i]) also if i is in the range of 0 to 3 of your example.
 If you work with arraypointers  you must always be sure that you reserve
enough memory. This can be done with malloc or I prefer calloc since this clears
to memory you get from your OS.

Hey ozo,

Why don't you give answers rather than comments?

You always get there first, then wait for someone else to give your comments as their answers

Since I can't tell what the questioner will consider an answer before
they comment back, I prefer not to lock the question until then.
Sometimes questions here seem to degenerate into a race to lock
rather than an attempt to find the best answer, and I don't want to
participate in such a competition.
Sometimes finding answers requires the cooperation of several commentators.
Others may have a different policy, but that's up to them.
The questioner always has the final say about what's an answer in any case.
Hey ozo,

I can't argue with that!!

Hats off to you


PS. Sorry John, for diverting from the topic

How do you allocate memory while the user inputs the strings with gets(string[i]);  this should allow the computer all the mem allocation for you right? John
