2.68♦♦
Write code for a function with the following prototype:
* Mask with least signficant n bits set to 1
* Examples: n = 6 -> 0x3F, n = 17-> 0x1FFFF
* Assume 1 <= n <= w
int lower_one_mask (int n);
Your function should follow the bit-level integer coding rules
Be careful of the case n = W.
Hi-Volt Components
You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit
boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys-
tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase
orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not
capable of handling EDI.
Tasks
1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur-
chasing system?
2. What terms or concepts describe the proposed computer-to-computer relationship between
Hi-Voltage and Green Industries?
why not?
3. Would Hi-Voltage's proposed new system be a transaction processing system? Why or
4. Before Hi-Voltage makes a final decision, should the company consider an ERP system? Why or
why not?
Consider the following expression in C: a/b > 0 && b/a > 0.What will be the result of evaluating this expression when a is zero? What will be the result when b is zero? Would it make sense to try to design a language in which this expression is guaranteed to evaluate to false when either a or b (but not both) is zero? Explain your answer
