Program to print binary right angle triangle

Binary right angle triangle consists of only 0’s and 1’s in alternate positions. 
Examples :

Input : 4
Output :
         0    
         1    0    
         0    1    0    
         1    0    1    0

Input : 3
Output : 
         0    
         1    0    
         0    1    0    

C++

// C program to print binary right angle

    for (row = 0; row < n; row++)
    {
        for (col = 0;col <= row; col++)
        {
