Answer:

  1. equation = input("Enter an equation: ")
  2. if("+" in equation):
  3.    operands = equation.split("+")
  4.    result = int(operands [0]) + int(operands[1])
  5.    print(operands[0] + "+" + operands[1] + "=" + str(result))
  6. elif("-" in equation):
  7.    operands = equation.split("-")
  8.    result= int(operands [0]) - int(operands[1])
  9.    print(operands[0] + "-" + operands[1] + "=" + str(result))  
  10. elif("*" in equation):
  11.    operands = equation.split("*")
  12.    result = int(operands [0]) * int(operands[1])
  13.    print(operands[0] + "*" + operands[1] + "=" + str(result))  
  14. elif("/" in equation):
  15.    operands = equation.split("/")
  16.    result = int(operands [0]) / int(operands[1])
  17.    print(operands[0] + "/" + operands[1] + "=" + str(result))  
  18. elif("%" in equation):
  19.    operands = equation.split("%")
  20.    result = int(operands [0]) % int(operands[1])
  21.    print(operands[0] + "%" + operands[1] + "=" + str(result))

Explanation:

The solution code is written in Python 3.

Firstly prompt user to enter an equation using input function (Line 1).

Create if-else if statements to check if operator "+", "-", "*", "/" and "%" exist in the input equation. If "+" is found (Line 3), use split method to get the individual operands from the equation by using "+" as separator (Line 5). Output the equation as required by the question using string concatenation method (Line 6).  The similar process is repeated for the rest of else if blocks (Line 7 - 22).

Instructions Write a program that allows the user to enter the last names of five candidates in a local election and the number
KengaRu [80]

Here is code in java.

import java.util.*;

class Election

{ //main method

   public static void main(String args[]){

      // create an object of Scanner class to read input

      Scanner s = new Scanner(System.in);

      // string array to store name of candidates

       String name[] = new String[5];

       // int array to store vote count of candidates

       int v_count[] = new int[5];

       double p = 0;

       int i = 0, sum = 0, high =0, win = 0;

for(i = 0; i < 5;i++)

       {

          System.out.print("last name of Candidate " + (i+1) + ":");

          // read name of Candidate

          name[i] = s.next();

          System.out.print(" number of votes received: ");

          // read vote of Candidate

           v_count[i] =s.nextInt();

if(v_count[i] > high)

              {

                  // highest vote

                  high = v_count[i];

                  win = i;

              }

              // total vote count

           sum +=v_count[i];

       }

     // printing the output

      System.out.println("\nCandidate\tVotes Received\t% of TotalVotes\n");

       for(i = 0; i < 5;i++)

       {

           // % of vote of each Candidate

           p =(v_count[i]*100)/sum;

           // print the output

          System.out.println(name[i] + "\t\t" + v_count[i] + "\t\t\t" +p);

       }

       // print the total votes

      System.out.println("\nTotal Votes:\t" + sum);

      // print the Winner of the Election

       System.out.println("Winner of the Election is: " + name[win]);

   }

}

Explanation:

Create a string array "name" to store the name of candidates.Create Integer array "v_count" to store votes os each candidates.Calculate total votes of all candidates and find the highest vote amongst all candidate and print it.Find % of votes received by each candidate.Print these stats.

Output:

last name of Candidate 1:patel

number of votes received: 54

last name of Candidate 2:singh

number of votes received: 76

last name of Candidate 3:roy

number of votes received: 33

last name of Candidate 4:yadav

number of votes received: 98

last name of Candidate 5:sharma

number of votes received: 50

Candidate       Votes Received  % of TotalVotes

patel           54                      17.0

singh           76                      24.0

roy             33                      10.0

yadav           98                      31.0

sharma          50                      16.0

Elena-2011 [213]

The term that describes the IP address of a router to which packets destined for a remote network should be sent by default is the a gateway of last resort.

<h3>What is 'Gateway Of Last Resort'? </h3>

A Gateway of Last Resort is known to be the Default gateway and this is said to be a route that is known to be often used by the router if no other known route is seen to transmit the IP packet.

Note that Known routes are seen in the routing table. but, any route not known by the routing table is said or known to be forwarded to the default route.

Hence the primary function of a router is so that it can forward packets toward a given destination.

Therefore, The term that describes the IP address of a router to which packets destined for a remote network should be sent by default is the a gateway of last resort.
