it can help you use C++ program we

#include <iostream >
using namespace std;

class CCounter
{
public:
	CCounter():m_val(0){ }
	~CCounter(){}

	unsigned GetVal()const { return m_val; }
	void SetVal(unsigned x) {m_val = x; }
	void Increment() { ++m_val; }  //自增函数，将变量的值加1

private:
	unsigned m_val;
};

int main()
{
	CCounter counter;
	cout << "counter的值是：" << counter.GetVal() << endl;
	counter.Increment();
	cout << "调用自增函数之后，";
	cout << "counter的值是：" << counter.GetVal() << endl;

	return 0;
}
