Can you explained this things
while using gets and puts, compiler saying warning why
fput.c.text+0x2a3): warning: the `gets' function is dangerous and
should not be used.

This is in the FAQ.

12.23: Why does everyone say not to use gets()?

A: Unlike fgets(), gets() cannot be told the size of the buffer
it's to read into, so it cannot be prevented from overflowing
that buffer. As a general rule, always use fgets(). See
question 7.1 for a code fragment illustrating the replacement of
gets() with fgets().
