Why is accessing a disk block expensive? discuss the time components involved in accessing a disk block. (?

Answer:

Explanation:

A disk block works by transferring data between the disk and main memory units which are called the blocks, whose size can range drastically from 512 bytes to several thousand.  This data is converted to hardware-level cylinder, surface, and sector number  which makes accessing the data immensely slower than accessing data in the main memory. This time constraint is also the main reason as to why accessing a disk block is so expensive.

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
rosijanka [135]

Answer:

#include <stdlib.h>

#include <time.h>

#include<iostream.h>

int main(void) {

   int seedVal = 0;  

   seedVal = 4;

   srand(seedVal);

  /* Solution*/

  cout<<rand() % 149 + 100<<endl;

  cout<<rand() % 149 + 100<<endl;

  return 0;

}

Explanation:

We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.

After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.

Your <span>cells don't have to be in the same order as your formula.</span>

What are the pros and cons of using unique closing reserved words on compound statements?
Nata [24]

Pros: Readability. Unique closing reserved words on compound statements will enhance readability and flexibility of a language. When an endwhile or an endif in a program is written by someone else, it is vivid which block is ending. Using braces is much harder is sometimes much harder to read.

Cons: Writability. They have the disadvantage of writability and thus, complicating the language by increasing the number of keywords. Use of more of these reserved words mean less words available for the programmer.
