C++ program to print 0 10 010 1010 pattern using class

Note: Use new compiler (Code blocks or Dev C++)  to run these C++ programs. Old  Turbo C compiler does not supports some new features of C++.

If you want to run these programs on old Turbo C++ compiler use <iostream.h> instead of <iostream> , do not use ( using namespace std; ) , use { getch(); } to hold run-time screen , use void main() instead of int main() .
