Cannot compile C++ code with Netbeans 7.0 on Mac OS

I am a new user to Netbeans and Mac OS both. I have a very simple C++ code

#include <iostream>
#include <string>

using namespace std;
int main()
{
    int i,count=0;
    char c;
    cin>>c;
    for (i=0;i<10;i++)
    {
           count=count+1;   

    }
    cout<<"count="<<count;      
}

I got the error below:

> "/usr开发者_如何学运维/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
"/usr/bin/make"  -f nbproject/Makefile-Debug.mk dist/Debug/GNU-MacOSX/azadeh

make[1]: *** [.build-conf] Error 2
make: *** [.build-impl] Error 2

>BUILD FAILED (exit value 2, total time: 60ms)

Does have anybody any idea how to solve this?

Thanks. Ehsan

You're linking two files together, and they both have main function defined. You need to remove one of those functions.
