Illegal operands, why the errors?

**Kons** · 08-26-2003

I am a noob at this quite honestly. I am trying to run a program that I found on the board and I am getting these errors. I am using Microsoft Visual C++.

What is the reason for these errors? and how would they be resolved?

Code:

h:\c\calendar.c(229) : error C2065: 'cout' : undeclared identifier
h:\c\calendar.c(229) : error C2297: '<<' : illegal, right operand has type 'char [9]'

Sounds like you didn't include the appropriate headers for cout.

What would the solution be? I just wanted to view the program...

I suppose I need the header files right? Where do I get those?

#include <iostream>
then the namespace bit:
using namespace std;
or
using std::cout;
or
std::cout <<"Something";

Thread moved to the C++ forum.

They came with your compiler. At least, they damn well should have.

I added iostream. The file needed to be renamed to .cpp

You should never include cpp files, only h (header) files.

No, I meant I renamed the prog to calendar.cpp and ran it and it worked fine.

It was named calendar.c

I think he means his source file. I'm guessing he had it as sdhfksd.c rather than sdhfksd.cpp, thus it used the C compiler not the C++.
