From the binary search algorithm, it follows that every iteration of the while loop cuts the size of the search list by half.
Colt1911 [192]

Answer:

True: In binary search algorithm, we follow the below steps sequentially:

Input: A sorted array  B[1,2,...n] of n items and one item x to be searched.

Output: The index of x in B if exists in B, 0 otherwise.

  1. low=1
  2. high=n
  3. while( low < high )
  4.  {      mid=low + (high-low)/2
  5.         if( B[mid]==x)
  6.          {
  7.             return(mid)  //returns mid as the index of x
  8.           }
  9.          else
  10.          {
  11.              if( B[mid] < x)      //takes only right half of the array
  12.               {
  13.                 low=mid+1
  14.               }
  15.              else               // takes only the left half of the array
  16.               {
  17.                high=mid-1
  18.               }
  19.           }
  20.  }
  21. return( 0 )

Explanation:

For each iteration the line number 11 or line number 15 will be executed.

Both lines, cut the array size to half of it and takes as the input for next iteration.

Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum
NemiM [27]

Answer:

The answer to this question as follows :

Structure definition:

struct Server  //define structure server.

{

string manufacturer;

 //define string variable.

string model, serialnum;  //define string variable.

int year;

 //define integer variable.

double clockSpeed;

 //define double variable.

int cores;   //define integer variable.

int ram;

    //define integer variable.

int storage;

  //define integer variable.

};

Explanation:

Structure is a collection of heterogeneous(different type) elements. It is a user-define datatype which is available on the C/C++ programming language. To define any structure we use the struct keyword. The syntax of defining structure can be given as:

Syntax:

struct structure name

{

//define variables

//statements and code.

};

OR

struct structure name

{

//define variables

//statements and code.

}create structure variable;  

In the above structure code, we define a structure that is "Server". In this structure, we define different types of variables that is " manufacturer, model, serialnum, year, clockSpeed, cores, ram, and storage". In this structure variable manufacturer, model and serialnum datatype are a string and clockSpeed datatype is double and variable year, cores, ram, and storage data type is an integer.

PHP Create a for loop that initialize with the variable $i = 10 The loop outputs $i as long as $i is greater than 1 using for lo
Tanzania [10]

Answer:

The PHP code is as follows

<?php

for ($i = 10; $i>1; $i--)

{

echo $i.' ';

}

?>

Explanation:

The code is self explanatory and doesn't require comments before it can easily understood.

The program starts with a php opening tag <?php

And it ends with the closing tag ?>

The interpretation of the question is to print integer values from 10 to 1

To do this, an iteration is needed.

The above program makes use of a for loop iteration.

Analysis;

for ( -> This shows that it is a for loop iteration

$i = 10; -> Iterating variable $i is initialized to 10 (that is; printing will start at 10)

$i>1; -> Iteration is valid while $i is greater than 1 (e.g. 2,3,4...10)

$i-- -> For every Iteration, decrease $i by 1

) -> End of Iterating condition

echo $i.' '; -> This line prints the valid values of $i. In this case, the values of $i is from 10 and stops at 2

The output is as follows

10 9 8 7 6 5 4 3 2
