The answer
Because loop variables naturally reset. The column resets to 1 on every new row, but Floyd's Triangle requires a continuous, non-resetting count.

Why can't I use the loop variables 'row' or 'col' for Floyd's Triangle?
More FAQs in Floyd's Triangle: Printing Sequential Numbers
Floyd's Triangle is a right-angled triangular array of natural numbers, where the numbers increment continuously without resetting on new rows.
Declare an accumulator or counter variable outside and above the outer loop, and increment it inside the innermost loop.
It is an architectural principle where the loops are solely responsible for coordinate mapping (the geometry), while external variables manage the actual data being inserted.
