How to initialize a variable array in a class?

class A

int i;
char array[1];
public:
A():i(0)

it should be static defined?

// In the header file

class MyClass
{
public:
	MyClass() {}
	~MyClass() {}

	static const char* ms_MyString;
};

// In the implementation file

const char* MyClass::ms_MyString = "0123456789";

// In the header file

class MyClass
{
public:
	MyClass() : m_MyString(0) {memset(m_MyOtherString, 0, 100);}
	~MyClass() {}

	char* m_MyString; // pointer-style array
	char m_MyOtherString[100]; // allocated array
};
