BaLLatris [955]

Answer:

import java.util.Scanner;

public class Division {

   public static void main(String[] args) {

    Scanner in = new Scanner(System.in);

       System.out.println("Enter an integer");

       int userNum = in.nextInt();

       System.out.println("Enter the divisor");

       int x = in.nextInt();

           int first = userNum/x;

           int second = first/x;

           int third = second/x;

           int fourth = third/x;

       System.out.println(first+" "+second+" "+third+" "+fourth);

   }

}

Explanation:

  • In Java programming langauge use the scanner class to receive the values from the user (userNum and x)
  • Carryout integer division of userNum/x to obtain the first number

Write a program sum.cpp that reads a sequence of integers from cin, and reports their sum. Example If you have a file numbers.tx
Katarina [22]

Answer:

The solution code is as follows:

  1. #include <iostream>
  2. #include <fstream>
  3. #include <string>
  4. using namespace std;
  5. int main()
  6. {
  7.    ifstream data;
  8.    float number;
  9.    float sum = 0;
  10.    
  11.    data.open("numbers.txt");
  12.    
  13.    while (data >> number) {
  14.        sum = sum + number;
  15.    }
  16.    cout<<sum;
  17.    return 0;
  18. }

Explanation:

Firstly, we create a ifstream object, <em>data</em> (Line 9). Then we can use the ifstream object to open the "numbers.txt" (Line 13) and use while loop to traverse through the number in the text file line by line (Line 15). White the loop is ongoing the number in each line is read by >> operator in a similar way to cin and then add each read number to sum variable (Line 16).

At last, display the output (Line 18).
