In this lab, you complete a C++ program that swaps values stored in three int variables and determines maximum and minimum values. The C++ file provided for this lab contains the necessary variable declarations, as well as the input and output statements. You want to end up with the smallest value stored in the variable named first and the largest value stored in the variable named third. You need to write the statements that compare the values and swap them if appropriate. Comments included in the code tell you where to write your statements.

Instructions

1.Ensure the Swap.cpp file is open in your editor.

2.Write the statements that test the first two integers, and swap them if necessary.

3.Write the statements that test the second and third integer, and swap them if necessary.

4.Write the statements that test the first and second integers again, and swap them if necessary.

5.Execute the program by clicking the Run button at the bottom of the screen using the following sets of input values.

// Swap.cpp – This program determines the minimum and maximum of three values input by

// the user and performs necessary swaps.

// Input: Three int values.

// Output: The numbers in numerical order.

#include

using namespace std;

int main

{

// Declare variables

int first = 0; // First number

int second = 0; // Second number

int third = 0; // Third number

int temp; // Used to swap numbers

const string SENTINEL = “done”; // Named constant for sentinel value

string repeat;

bool notDone = true; //loop control

// Get user input

cout << "Enter first number: ";
cin >> first;

cout << "Enter second number: ";
cin >> second;

cout << "Enter third number: ";
cin >> third;

while(notDone == true) //defining a loop to check the value

// Test to see if the first number is greater than the second number

// Test to see if the second number is greater than the third number

// Test to see if the first number is greater than the second number again

// Print numbers in numerical order

cout << "Smallest: " << first << endl;
cout << "Next smallest: " << second << endl;
cout << "Largest: " << third << endl;
cout << "Enter any letter to continue or done to quit: ";
cin >> repeat;

if (repeat == SENTINEL){

notDone = false;

} else {

cout << "Enter first number: ";
cin >> first;

cout << "Enter second number: ";
cin >> second;

cout << "Enter third number: ";
cin >> third;

}

return 0;

} // End of main function
