 Use the format specified earlier (initial block of comments with TCC logo, name, etc)

Display instructions so that the user understands the purpose of the program and what to enter.

Display the results in increasing (non-decreasing) order.

Run the program for the following 6 test cases.Turn in a printout of the program and printouts of the 6 test cases.(The result should be the same in all 6 cases!)

Case 1stnumberentered 2ndnumberentered 3rdnumberentered

1 10 20 30

2 10 30 20

3 20 10 30

5 30 10 20

6 30 20 10

Answer 1

#include <iostream>

using namespace std;

int main()
{
int num1, num2, num3, smallest, middle, biggest;
cout<< "Enter first number:\t";
cin>> num1;
cout<< "Enter second number:\t";
cin>> num2;
cout<< "Enter third number:\t";
cin>> num3;
  
if ((num1 < num2) && (num1 < num3))
{
smallest = num1;
if (num2 > num3)
{
biggest = num2;
middle = num3;
}
}
  
if ((num1 < num2) && (num3 << num1))
{
smallest = num1;
if (num2 < num3)
{
middle = num2;
biggest = num3;
}
}
if ((num1 > num2) && (num3 > num1))
{
middle = num1;
if (num2 < num3)
{
smallest = num2;
biggest = num3;
}
}
  
if ((num1 < num2) && (num3 < num1))
{
middle = num1;
if (num2 > num3)
{
biggest = num2;
smallest = num3;
}
}
if ((num1 > num2) && (num1 > num3))
{
biggest = num1;
if (num3 > num2)
{
middle = num3;
smallest = num2;
}
}
  
if ((num1 > num2) && (num1 > num3))
{
biggest = num1;
if (num2 > num3)
{
middle = num2;
smallest = num3;
}
}

cout<< "Ascending order is : ";
cout << smallest << ", " << middle << ", " << biggest << endl;
  return 0;
