Answer 2

fflush flushes everything from the buffer, in this case for stdin. so if you have read some data but there is more buffered still it will clear it.

Answer 3

but if it is used only when we use int and char simultaneously
but when we use int and float do we use it?i dont think so...

Answer 4

fflish(stdin) =>clears the input buffer and it doesn't know it is int,char,float,double.It just flushes buffer.

Answer 5

my point is that we regularly use fflush(stdin)
when we want to read int and char simultaneously
but when we read int and float we don use it
y??
