Answer:

The correct answer is: Option 2: #

Explanation:

Comments are additional information that is added to a program. The comments help the person who is viewing or reviewing the program to understand logic or function and variable definitions.

In Python, comments are added using the # symbol and adding a white space after it.

The interpreter doesn't interpret the comment section of the program.

Hence,

Answer:

Explanation:

Since no programming language is stated, I'll use Microsoft Visual C# in answering this question.

// C# program sort an array in ascending order

using System;

class SortingArray {

int n; //number of array elements

int [] numbers; //Array declaration

public static void Main() {

n = Convert.ToInt32(Console.ReadLine());

numbers = new int[n];

for(int i = 0; i<n; I++)

{

numbers [n] = Convert.ToInt32(Console.ReadLine());

}

SortArray();

foreach(int value in numbers)

{

Console.Write(value + " ");

}

void SortArray()

{

int temp;

// traverse 0 to array length

for (int i = 0; i < numbers.Length - 1; i++)

// traverse i+1 to array length

for (int j = i + 1; j < numbers.Length; j++){

// compare array element with all next element

if (numbers[i] < numbers[j])

{

temp = numbers[i];

numbers[i] = numbers[j];

numbers[j] = temp;

}

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a

kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = $\frac{CPI*Instruction Count}{ClockRate}$

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

for system B CPU time is $=\frac{2.5*100,000}{750*10^6}$

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = = $\frac{2.5*Instruction}{750*10^6}$

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A
