Pattern Problem, column should be incremented

#1

In solution, where even row code starts, first bhaiya did cout<<1 for col variable 1, then he moved on to print zeroes but didn’t incremented column. Can you tell I am wrong or right?

#2

yes column is not incremented because it is not needed
bhaiya first print 1
and then print n-2 zeroes
and then at last print 1

col is just a variable it will be increment inside loop only

i hope you understand the point
if not let me know
