puts() replaces with a new line in the output.

#include <stdio.h>

main()

{

char line[80], *gets();

while((gets(line)) != NULL)

puts(line);

}

To terminate this program, generate an end of ﬁle on stdin. Using string comparison and

string length functions, you can write a termination condition for this program.
