Private/Public Example

class Test
{
public:

	void displayPrivateNo()
	{
		std::cout << privateNo << std::endl;
	}

private:
	int privateNo{ 1337 };
};

int main()
{
	Test test;

	test.displayPrivateNo(); //Works because displayPrivateNo calls the integer privateNo within the class
	//std::cout << test.privateNo << std::endl; //Doesnt work because privateNo gets called outside of the class

	system("pause");
	return 0;
