Write a C++ program to prompt the user to input 3 integer values and print these values in Forward [Ascending] order

Assignment 3 (B)

Write a
C++ program to prompt the user to input 3 integer values and print these values
in Forward
[Ascending] order.

Program
Code with explanation [ Without loop ]:

1.   
#include
<iostream>

2.   
using
namespace std;

3.   
int
main()

4.   
{

5.   
      int
a1,a2,a3;

6.   
      cout<<“Accept
three integer values to display Forward [Ascending] order “;

7.   
      cout<<“\nAccept
First Number “;

8.   
      cin>>a1;

9.   
      cout<<“\nAccept
Second Number “;

10.       cin>>a2;

11.       cout<<“\nAccept
third Number “;

12.       cin>>a3;

13.       cout<<“Display
Forward [Ascending] order \n”;

14.       //
Sort numbers without using Loop.

15.       if((a1<a2)&(a1<a3))

16.       {

17.                   cout<<“\n”<<a1<<“\t”;

18.                   if(a2<a3)

19.                               cout<<a2<<“\t”<<a3;

20.                   else

21.                               cout<<a3<<“\t”<<a2;

22.       }

23.       if((a2<a1)&(a2<a3))

24.       {

25.                   cout<<“\n”<<a2<<“\t”;

26.                   if(a1<a3)

27.                               cout<<a1<<“\t”<<a3;

28.                   else

29.                               cout<<a3<<“\t”<<a1;

30.       }

31.       if((a3<a1)&(a3<a2))

32.       {

33.                   cout<<“\n”<<a3<<“\t”;

34.                   if(a1<a2)

35.                               cout<<a1<<“\t”<<a2;

36.                   else

37.                               cout<<a2<<“\t”<<a1;

38.       }

39.       return
0;

40.       }

Explanation
of Code:

Line
No. 1 and 2: include the Library file and stander input – output functions.

Line
No. 3: main function header.

Line
No. 4 and 40: Begin and end of main function respectively.

Line
No. 5: Declare the three integer variables.

Line
No. 6 to 12: Accept three integer numbers with appropriate massage. 

Line
No. 13 and 14: Display massage “Display Forward [Ascending] order”.

Line No. 15: To check first
integer number less than other than two if it’s true then goes to Line No 17
and print first number.

Line No. 18: To check second  integer number less than third integer number
if it’s true then goes to Line No 19 and print second and third integer number
respectively. Otherwise goes to 21 and print third and second integer number
respectively.

Repeat same process for check second and third number at Line No 23 to 30 and 31 to 38 respectively.

Program
Code for run:

#include
<iostream>

using
namespace std;

int
main()

{

    int a1,a2,a3;

    cout<<“Accept three integer
values to display Forward [Ascending] order “;

    cout<<“\nAccept First Number
“;

    cin>>a1;

    cout<<“\nAccept Second Number
“;

    cin>>a2;

    cout<<“\nAccept third Number
“;

    cin>>a3;

    cout<<“Display Forward [Ascending] order \n”;

    // Sort numbers without using Loop.

    if((a1<a2)&(a1<a3))

    {

       
cout<<“\n”<<a1<<“\t”;

        if(a2<a3)

           
cout<<a2<<“\t”<<a3;

        else

           
cout<<a3<<“\t”<<a2;

    }

   

    if((a2<a1)&(a2<a3))

    {

       
cout<<“\n”<<a2<<“\t”;

        if(a1<a3)

           
cout<<a1<<“\t”<<a3;

        else

           
cout<<a3<<“\t”<<a1;

    }

   

    if((a3<a1)&(a3<a2))

    {

       
cout<<“\n”<<a3<<“\t”;

        if(a1<a2)

           
cout<<a1<<“\t”<<a2;

        else

           
cout<<a2<<“\t”<<a1;

    }

    return 0;

}

Output
of Program:

Accept
three integer values to display Forward [Ascending] order

Accept
First Number  3

Accept
Second Number  1

Accept
third Number  2

Display
Forward [Ascending] order

1          2          3
