Let's consider a long, quiet country road with houses scattered very sparsely along it. (We can picture the road as a long line

segment, with an eastern endpoint and a western endpoint.) Further, let's suppose that despite the bucolic setting, the residents of all these houses are avid cell phone users. You want to place cell phone base stations at certain points along the road, so that every house is within four miles of one of the base stations. Give an efficient algorithm that achieves this goal, using as few base stations as possible.

Answer:

Follows are the solution to these question:

Explanation:

A simple gullible algorithm is present. Let h mark the house to the left. Then we put a base station about 4 kilometers to the right. Now delete and repeat all the houses protected by this base station. In this algorithm, they can simply be seen to position baselines at b1, . . , bk as well as other algorithms (which may be an optimum algorithm) at b'_{1}, \ . . . . . . ,b'_{k'}  and so on. (from left to right)   b_1 \geq b'_{1},\ \  b_2 \geq b'_{2} That's why k \leq k'.

Write a program that prints the U.S. presidential election years from 1792 to present day, knowing that such elections occur eve
miv72 [106K]

Answer:

The cpp program to print US presidential years is given.

#include <iostream>

using namespace std;

int main()

{

   // variable to hold presidential election year declared  

   int elec_year;

// variable to hold presidential election year initialized to 1792  

elec_year=1792;

   

// the value displayed on the console output

   std::cout << "The U.S. presidential election years from 1792 to present day are listed. " << std::endl;

   

   // loop executes till year is less than or equals 2020

   do

   {

       // initial value is printed

       std::cout << elec_year << std::endl;

       

       // value is incremented by 4

       elec_year = elec_year + 4;

       

   }while(elec_year<=2020);

   return 0;

}

OUTPUT

The U.S. presidential election years from 1792 to present day are listed.

Explanation:

The program works as described.

1. An integer variable, elec_year, is declared and initialized with the first US presidential year value, 1792.

2. Inside the do-while loop, the variable, elec_year, is first printed to the console followed by a new line inserted using, endl.

3. The variable, elec_year, is then incremented by 4.

4. The do-while loop continues till the value of the variable, elec_year, does not exceeds the current year, 2020.

5. The program ends with a return statement since main() has return type int.

6. Only one variable is used in the program.

7. The program consists of only main() method since cpp is not completely object oriented programming language.

8. The same program, if written in object oriented programming language like java or c# will be written inside a class and executed through main() method.
