Answer:

Depending on exactly what they mean by read and write, both A and D are valid.  In fact, if you read that as "read or write" as being a logical OR and not the logical AND that the sentence probably intends, then all four answers could be correct.

What they probably mean to say though is "..... is used as a read/write storage medium", in which case A is the correct answer.

A.  Data can be written to or read from a CD.  This is probably the "right" answer

B. A human can "read" data from a Visual Display Unit, and the computer "write" it.  That of course is not the intended meaning though.

C.  Data can be read from Read Only Memory, but not written to.

D. Data can be both read and written to Random Access Memory, but not retained after the computer is powered off.

Explanation:

The below code has been written in C language

void rotateright(int list[], int n)

{

  int x = list[n-1]

  int i;

  for (i = n-1; i > 0; i--)

     list[i] = list[i-1];

  list[0] = x;

}

void rotateleft(int list[], int n)

{

  int x = list[0]

  int i;

  for (i = 1; i < n-1 ; i++)

     list[i] = list[i+1];

  list[n-1] = x;

}

int main()

{

   int list[] = {x1, x2, x3, ... x(n-1),xn}

   int i;

   int n = sizeof(list);

       

   rotateright(list, n);

 

   rotateleft(list, n);

   

   return 0;

HELP PLEASE!!!! Which development method is best explained in this way: developing a system through repeated cycles and smaller
vlada-n [284]

Answer:

Incremental method.

Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.

In SDLC, a waterfall model can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

Also, a spiral model can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
