When is this possible, if the programmer always uses <, not <=?

Question

Consider two declarations for the loop:

for (int i = 0; i < 70; ++i)

and

for (int i = 0; i <= 69; ++i)

I assume the second will do 139 full comparisons, not 69. Is my assumption correct? I am not an electrical engineer, so I don’t know how ALU works, regardless of whether it makes the “less than or equal to” thingamabob in one fell swoop or what.

Can you give an example of use <=?

By the way, I'm trying to become a "hardcore" programmer like you guys.

Answer 2

, 70 69 .

, 70, 70 .

, 1 :

for i = 1, i <= 70

0:

for i = 0, i < 70
