How to make Hello World in Netbeans?

[dorlow]

I am trying to write a simple Hello World in Netbeans. My host OS is Open Suse. I downloaded Netbeans with c++. I went into plugins and enabled c++. I start a c/c++ app and select c++ in the drop down menu in the wizard. I then go into main and enter cout << "hello world."


When typing the code in the IDE, it puts the red squiggleys under cout which tells me something is way wrong if it doesn't know cout. What am I doing wrong?

#include <cstdlib>

using namespace std;

int main(int argc, char** argv) {
    cout << "Hello World\n";

    return 0;
}

std::cout is not part of the C stdlib (<cstdlib>) library, you have to include <iostream>.

#include <iostream>

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

I tried both iostream and iostream.h and same thing...

#include <iostream.h>

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

Your gcc configuration (line 9) "smells" a bit odd, -std=c99 is using the C99 standard to compile. It should be -std=c++11.

I don't use Netbeans for compiling C/C++ code. Other than a possible setup configuration problem I don't have a clue.

It seems more like a C project.
Try this:

#include <stdlib.h>
#include <stdio.h>

int main() 
{
  printf("Hello world");
  getchar();

 return 0;
}
