Thread: problem in Object Oriented

Do not be frustrated to read if the code looks too long but it is very simple program. I am new in programing and I have done it without using the object oriented design , but for this one I have to use the object oriented design. So, I compiled the program and it has these following errors:

Error E2040 workingArea2.cpp 6: Declaration terminated incorrectly
Error E2040 workingArea2.cpp 17: Declaration terminated incorrectly
Error E2275 workingArea2.cpp 29: { expected
Error E2321 workingArea2.cpp 165: Declaration does not specify a tag or an identifier
Error E2268 workingArea2.cpp 181: Call to undefined function 'newCode' in function main()
*** 5 errors in Compile ***


I am sure about the codes because I just copied them from the previous program that works the same. I am not sure how does the object oriented design look like so after reading a lot of topics about the object oriented design I came up with this style but I am not really sure about it. So, anyone has any hint or comment on my code that I should change ?

Code:

#include <iostream>

using namespace std;


void SteptsCode()
{

		cout << "   1. The digits 4 and 5 must appear at least once.\n";
		cout << "   2. Either the digit 8 and 9 must appear at least once.\n";
		cout << "   3. The only valid letters are A,L,P,R,T,V,W, and X.\n";
		cout << "   3. Each four-character subsquence (1-4, 5-8, 9-12) must contaon at least one digit and at least one letter.\n";
		cout << "  \n"<<endl;
};	

// If all the conditions are valid, all the characters will be stored in an array from newCode(). Then, this method is going to print the code
class printCode()
{
	int i=0;
	string billy [12];

	public:
	for( i = 0; i< 13; i++)
	{
		cout<<billy[i]<<endl;
	}
};
