Question

• • Uses a while loop to print the numbers from 3 - 19.
  • Uses a do-while loop to print the numbers from 42 - 56.
  • Uses a for loop to print the numbers from 87 - 95.
  • Asks the user for 2 numbers. Uses a loop to print all numbers between the given numbers, inclusive.
    • Note: Consider that your user's second number can be lower! (see example below)
    • Note: Also consider that your user might give you two of the same number.
• Your program MUST:
  • Use a while, do-while, and for loop. The fourth loop is your choice.
  • Actively use in-line comments stating what each section of code does.
  • Use try/catch, BUT only if necessary.
  • Your program must conform to the Java coding standards
  • This is an example of what your program should output:

• I'm going to print out the numbers 3-19 using a while loop:
  3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
  
  I'm going to print out the numbers 42-56 using a do-while loop:
  42 43 44 45 46 47 48 49 50 51 52 53 54 55 56
  
  I'm going to print out the numbers 87-95 using a for loop:
  87 88 89 90 91 92 93 94 95
  
  Now I'll print whatever numbers you'd like!
  Give me a starting number:
  2
  Give me an ending number:
  -4
  I see that your ending number is lower. Okay, I'll count down!
  2 1 0 -1 -2 -3 -4

#include<iostream>
using namespace std;

main()
{
    int i=3;
    while(i<=19)
    {
        cout<<i<<" ";
        i++;
    }
    cout<<endl;
    int j=42;
    do
    {
        cout<<j<<" ";
        j++;
    }while(j<=56);

    cout<<endl;
    for(int k=87;k<=95;k++)
        cout<<k<<" ";

    cout<<endl;
    cout<<"enter two numbers"<<endl;
    int x,y;
    cin>>x>>y;
    if(x<=y)
    {
        for(int a=x;a<=y;a++)
        cout<<a<<" ";
        cout<<endl;
    }
    else
    {
        for(int a=x;a>=y;a--)
            cout<<a<<" ";
        cout<<endl;
    }
    return 0;
}
