Answer:
a) AL will contains 0011 1100
Explanation:
In assembly language, shifting bits in registers is a common and important practice. One of the shifting operations is the SHR AL, x where the x specifies that the bits be shifted to the right by x places.
SHR AL, 2 therefore means that the bits contained in the AL should be shifted to the right by two (2) places.
For example, if the AL contains binary 1000 1111, the SHR AL, 2 operation will cause the following to happen
Original bit => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 |
Shift once to the right => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | (0) |
Shift once to the right => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | (0) | (0) |
Notice;
(i) that there are two shifts - one at a time.
(ii) that the bits in bold face are the bits in the AL after the shift. Those that in regular face are those in the carry flag.
(iii) that the new bits added to the AL after a shift are the ones in bracket. They are always set to 0.
Answer:
Answer is b. 10
Explanation:
The find() method is used to search the string for a specified value and searches the first occurrence of that value. It returns the position of that specified value. If the value is not found, this method returns -1.
Lets say we have a message variable that contains the string Happy holidays.
message = "Happy holidays"
We use the method find() to find days word from the Happy holidays string in the message variable.
The find() method will find the position of day.
If we look at the string Happy holidays we see that the word day is at the 10th position of the string.
H 1
a 2
p 3
p 4
y 5
h 6
o 7
l 8
i 9
d 10
a 11
y 12
s 13
So it is at 10th position so the statement
message.find("days")
returns 10
You should select the text by clicking and holding the mouse at the beginning of the text and then dragging it to the end of the area you want to change. You can also use the arrow keys and hold shift, but this takes longer typically.
Answer:
The team did not adequately formalize the software's design
Explanation:
The most logical reason for this confusion is the fact that the team did not adequately formalize the the software design.
The design approach has to do with clearly defining the architectural modules of the application. The requirements in the software requirement specification document would serve as input for the next phase. The documents are prepared and they give a definition of the overall system architecture.
The team got confused because they did not go through this phase of the 10-phase SDLC model.
