A program uses 4 bits to store numbers. When it adds 10 and 7, the result is 1. Which of the following best explains why? 1) the program is reporting the number of bits required to compute the sum
2) an overflow error led the program to reset to O at the number 16
3) 1" is an error code that indicates a rounding error
4) 4 bits is not enough to represent the number 10, so the computer reported only the tens value
