l can be very hard to read. This is because the letter
I and the letter
l are easily confused, and the letter
O and the number
0 can be easily confused.
Change the names of these variables to something more descriptive.
The code in this example could be misinterpreted to be
0 * 1.08 (zero times one-point-eight).
O = 100.0 total = O * 1.08
This example clarifies that we’re multiplying an
order variable by another number.
order = 100.0 total = order * 1.08
