Question

Write a C++ program in this new file.

1. (1 point) Accept 10 integers from the user using an array and a loop.
2. (2 points) Print the numbers in reverse order from the order in which they were entered.
3. (4 points) Sort the array from lowest to highest number and print the numbers in this new, sorted order.

Answer 1

1. (1 point) Accept 10 integers from the user using an array and a loop.

#include<iostream.h>

#include<conio.h>

void main()

{

            clrscr();

            int arr[10], i;

            cout<<"Enter array elements : ";

            for(i=0; i<10; i++)

            {

                        cin>>arr[i];

            }

            getch();

}

2. (2 points) Print the numbers in reverse order from the order in which they were entered.

#include<iostream.h>

#include<conio.h>

void main()

{

            clrscr();

            int arr[50], size, i;

            cout<<"Enter array size : ";

            cin>>size;

            cout<<"Enter array elements : ";

            for(i=0; i<size; i++)

            {

                        cin>>arr[i];

            }

            cout<<"Now the Reverse of the Array is : \n";

            for(i=size-1; i>=0; i--)

            {

                        cout<<arr[i]<<" ";

            }

            getch();

}

3. (4 points) Sort the array from lowest to highest number and print the numbers in this new, sorted order.

#include <iostream.h>

#include<conio.h>             

void main()                       

{

            int a[100],n,i,j,tmp;

            cout<<"Array size: ";

            cin>>n;

            cout<<"Elements: ";

      for(i=0;i<n;i++)

    {

            cin>>a[i];

    }

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

            {

                        for (j = 0; j < n; j++)            

                        {

                                    if (a[j] > a[i])                                          {

                                                int tmp = a[i];        

                                                a[i] = a[j];           

                                                a[j] = tmp;            

                                    }

                        }

            }

            cout<<"\n\nAscending : ";                    

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

          {

            cout<<"\n";

                        cout<<a[i];

            }

            getch();

}
