Thread: Complie and link C++ code in C

Hello people,
it's been a long since last time I worked with C and C++. Is it possible to link Cpp code in C?
What I mean is this:
In basics, it comes to this...

I have two files:
Test_cpp.h

Code:

int test_cpp(int);

Test_cpp.cpp

Code:

int test_cpp(int x)
{
    return x+2;
}

and main.c /*in other C project in which Test_cpp.h and Test_cpp.cpp are included*/

Code:

#include <stdio.h>
#include "Test_CPP.h"

int main(int argc, char *argv[])
{
  printf("&#37;d", test_cpp(4));
  return 0;
}

Is it possible to use extern keyword to make this work?

Thanks
