How many times will the following loop run?

Question

for(char c=0; c<266; ++c)
{}

Answer 1

Infinitely. ASCII table has 128 characters (they hold values between 0 and 127).
Maximum value (127) + 1 gives a minimum value, so 266 won't be reached.

Answer 2

it is an infinite loop
this is known as overflow of signed char

Answer 3

sorry, ignore my previous answer. i didn't pay close attention and didn't see that it wasn't an int.
