A variable of type unsigned char stores a value of 255. If the variable value is decremented, what exception will occur

No exception will occur

Explanation:

Given

Unsigned Char

Value  = 255

Operation = Decrement

Required

What type of exception occurs?

Let's assume the variable is a.

So, we have that

a = 255

The range of values of an unsigned char a is 0 to 255

So, when a is decremented by 1, the new value of a becomes 254

254 is still within the range of 0 to 255.

Hence, no exception will (or is excepted to) occur
