Answer:
(10000000)₂ = -128 in decimal
(11001100)₂ = -52 in decimal
(10110111)₂ = -73 in decimal
Explanation:
<u>NOTE:</u> If Most Significant Bit is 0, it is positive number and if MSB is 1, it is negative number. If number is positive we can simply convert it to decimal. But if number is negative, follow following formula:
- (complement of the number) +1
<u>EXAMPLE 1</u>
(10000000)₂
(01 1 1 1 1 1 1)₂ ↔ complement of the number
<u>+ 1</u>
(10000000)₂ = 1 ×
= 128 (magnitude in decimal)
But we remember MSB was 1 so answer is -128.
<u>EXAMPLE 2</u>
(1 1 0 0 1 1 00)₂
(0 0 1 1 0 0 1 1)₂
<u>+ 1 </u>
(0 0 1 1 0 1 0 0)₂ = 52 (magnitude in decimal)
But we remember MSB was 1 so answer is -52.
<u>EXAMPLE 3</u>
(1 0 1 1 0 1 1 1)₂
(0 1 00 1 000)₂
<u>+ 1 </u>
(01 00 1 00 1)₂ = 73 (magnitude in decimal)
But we remember MSB was 1 so answer is -73.
Answer:
Maintenance Phase
Explanation:
One of the concepts employed in project management for describing stages involved when carrying out an information system development project is the systems development life cycle (SLDC). The cycle which starts from carrying out a feasibility study and ends in maintenance is a highly used conceptual model. There are 5 major stages or phase and they are the; Requirement Phase, Design Phase; Implementation Phase, Test Phase, and the Maintenance phase. The maintenance phase comes when testing has been complete and all enhancement and modifications have already been developed, and the system is operating.
Answer:
The buffer has room for 499 characters (you always have to reserve 1 for the terminating \0 character).
The code copies all characters passed in the commandline (argv[1]) into this buffer without checking. If there are more than 499 characters supplied, these will be copied into a memory location that is not intended for it. This will probably cause your program to crash, but if the extra data is somehow executed by the processor as if it were a program, this could be a way to sneak a virus into your computer.
So, while copying data, it is important to always limit the maximum amount to the allocated space.
Idk what is it?
