I tried to make a calculator by c++ but when I build and run a message appears [error] iostream.h No suchfile or directory

Question

what does this mean?

Answer 1

the error means the directry youve included doesnt exist.i thought its
<iostream> not iostream.h?

Answer 2

there's no such file named "iostream.h",instead "iostream" exists.So change "#include <iostream.h>" to "#include <iostream>"

Answer 3

thanks guys, but is only iostream enough to make a calculator? what about <conio> and <process>?

Answer 4

and how I can use them all at the same time?

Answer 5

the compiler still sends a message [error]

Answer 6

I'm confused

Answer 7

when i made my c++ calculator i only used
<cmath>
<iostream>

Answer 8

oh thanks again
