Title: Hello World Fail
Post by: zhousama on February 21, 2014, 09:26:00 pm

Hello,

I'm just starting to learn C++ and installed Codeblocks. I copied the HelloWorld program but immediately get an error:
C:\Users\...\New folder\Untitled5.c|2|fatal error: iostream: No such file or directory|
||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

This is the program:
// my first program in C++
#include <iostream>

int main()
{
  std::cout << "Hello World!";
}

I'm think the error lies in the standard libraries not being included in the build path, but I'm not sure which directories to include. Any ideas?

Thanks in advance!

you are trying to compile a c++ program with a c compiler. C::B looks at the file ending to get the right compiler. So if you want to compile a c++ program  (iostream) your file needs the cpp or cxx ending and not c.

int main requires a return type.

BlueHazzard is correct in the cause.
