This is a pretty basic question, and I suggest you get a better understanding of pointers in general because they are a key part to C/C++.

Start by reading this:

CMyClass
{
public:
int m_nValue;
};

void MyFunc()
{
CMyClass MyClass;
IncValue(&MyClass);
}

void IncValue(CMyClass* pMyClass)
{
pMyClass->m_nValue++;
}
