See more:

#include<iostream>
#include<cstdlib>
using namespace std;

int main() {

	// Providing a seed value
	srand((unsigned)time(NULL));

	// Get a random number
	int random = 1 + (rand() % 10);

	// Print the random number
	cout << random << endl;

	return 1;
}

The code works just fine in MS VC++.

You're going to have to supply the error message you're getting if you want help to get this fixed.

Probably, it does. Just too quickly for you to see.
Your code creates a console app, which if if press "Run" in VS opens a console, writes to it, and closes the console window - probably faster that the paint requests reach the console itself. So it runs and ends before anything becomes visible!

Try adding a breakpoint at the return line and run it in the VS debugger. You should be able to see what it happening then.

Care to share what error is?

Edit: Returning 1 from the main() signals an error, try returning 0 instead.

That many probably means syntax errors - so start here:
