Gets() in c program

Question

I did not understand why is
char[100];
gets(a);
is written what is the meaning of it?

Answer 1

gets() is function used to read the line of stings from standard input into argument charecter array a.

Check this by
gets(a);
puts(a); //outputs what ever read by gets() into a.

gets() is a non-standard deprecated function. So recommend that avoid using gets() instead use fgets()..
