2010 - Homework #5

Functions

Write your programs in your 2010/5 folder on Odin.

Part-1

We started this program in class together.

Name your program: 2010/5/order3.cpp

Prompt the user for 3 numbers.
After entry, display all 3 numbers in order from low to high.

sample output...

 $ ./a.out

 Please enter 3 numbers: 6 14 3

 Your numbers in-order are: 3 6 14




Rules:
   No assignment operators are allowed in your program.
   No calls to swap are allowed.
   No math operators are allowed.
   There is no input validation.
   The output text must be just as shown in the sample.
   One space before each number.

Code:
   Store the input numbers in 3 different variables.
   Use if-statements to arrange the numbers for output.

    Start with this code from class Wednesday.
    A small fix was made to the code from class.
    Test and adjust your own code.

    if (a <= b && a <= c && b <= c) {
        cout << a << " " << b << " " << c << endl;
    }
    else if (a <= b && a <= c && c <= b) {
        cout << a << " " << c << " " << b << endl;
    }


   Test with input like this:
   
   a b c
   - - -
   2 3 4   <---- a is lowest
   3 2 4   <---- b is lowest
   3 4 2   <---- c is lowest
   3 4 4   <---- a is lowest, but b & c are equal
   4 3 3   <---- a is highest, but b & c are equal
   4 4 2   <---- c is lowest, but a & b are equal

For easier testing of your program, run it like this...
This is called directed input.



  $ ./a.out <<< "3 4 2"

  Please enter 3 numbers: 
  Your numbers in-order are: 2 3 4





For some extra credit...

Make your order3 program get 3 numbers from the command-line.

You can leave your cin statements in your program, but if there
are 3 numbers on the command-line, then skip around your cin
statements using an if-statement.

This way, your program can get input in 3 different ways...
    cin, command-line, or directed input.

sample run...


 $ ./a.out 3 4 2

 Your numbers in-order are: 2 3 4
