Can we make a c++ program without iostream header file?

Question

i am confused about it, is it possible on c or in c++

Answer 1

You can exclude iostream header file but then you can't use its objects e.g cin, or any other for any input output operations.
As far as I know, in C we don't have iostream header file, instead we include stdio.h and use its functions, e.g printf() & scanf().

Answer 2

by using header file as fstream as fstream contains iostream

Answer 3

Yes if you do not need them ^^
But it does not happen often

Answer 4

Yes you can if you don't need to use cin or cout or we can say basic input output.
