Thread: stupid question

hi i am having trouble compiling my program i think the problem is probably very simple but i cant figure it out

Code:

#include<iostream>

main(){
	char c[]="hi\n";
	stdout << c;

	return 0;
}

i am using microsoft visual c++ here is what the error message is C:\Programs\calculator\test.cpp(5) : error C2296: '<<' : illegal, left operand has type 'struct _iobuf *'
C:\Programs\calculator\test.cpp(5) : error C2297: '<<' : illegal, right operand has type 'char [22]'

stdout is not declared anywhere. In C++ cout is the standard/default stream object used to display to the standard output unit (that is to display to the screen). Given your use of the iostream without the .h you will need to indicate namespace somehow. Adding the line


using namespace std;

between the first and third line of your program is probably the simplest, though not necessarily the best, approach to indicating namespace for now.

is there anyway to declare an output or input stream yourself or do you have to use the iostream include?

You can't declare an ostream or an istream because they'll keep all constructors away from you. You can create new stream objects with your own implimentations if you absolutely needed/wanted to.
