Answer:
256
Explanation:
The largest number that can be represented using 8 bits (8 positions of binary 1 or 0) is 255. This is assuming that the 8 bits are being used to represent only positive integer values. In 8-bit binary, the decimal number is represented as 11111111. This means that if you have an 8-bit integer variable with a decimal value of 255 stored in it (again, 11111111 in binary) and you attempt to add 1 more to it (255 + 1), the answer is 256. 256 would require a 9th bit of storage to represent it (100000000 in 9-bit binary) properly, and since the number is limited to 8 bits of storage, the system will throw an overflow error. Overflow errors happen when you try to store a number in variable that is too small to hold the value.
Fun Fact: most modern computers use 64-bit system architecture. This means that the largest number you can put into a single 64-bit integer variable is 9,007,199,254,740,992. Adding 1 to that would, as you've probably guessed, cause an overflow error.
