I need to add some methods to Z as virtual ones so that they will be overridden in Z child classes Z1, Z2, .. Zn.

Is it possible, how can I do it.

#pragma omp parallel num_threads(3)
{
     ... some code for 3 cores
}

	// Get the number of processors in this system
	int iCPU = 0;
	iCPU = omp_get_num_procs();
	cout << "# of CPU's " << dec << +iCPU << endl;

gets "4" which is number of CPU's 

	int iMAXThread = 0;
	iMAXThread = omp_get_max_threads();

	cout << "# of iMAXThread " << dec << +iMAXThread << endl;

also gets "4" - apparently default of "one thread to CPU ?" 



	// Now set the number of threads 
	omp_set_num_threads(10);

	iMAXThread = omp_get_max_threads();

returns "10" per "system ?" 

	cout << "# of iMAXThread " << dec << +iMAXThread << endl;

	exit(1);

<div class="op">Quote:</div>$ cat example.c 
 #include <omp.h>

int main()
{
 #pragma omp parallel
    {
        int ID = omp_get_thread_num();
        printf("hello(%d)", ID);
        printf("world(%d)\n", ID);
    }

    return 0;
}
$ gcc -fopenmp example.c -o example

hello(1)world(1)
hello(0)world(0)
hello(3)world(3)

$ ./example
hello(3)world(3)

hello(1)world(1)

int omp_get_num_procs();

I have noticed that some code posts here include manually building the "make".
Why if run of the mill IDE does it "automatically" ?
