C++. Write a program that reads three integers from cin and outputs them in order from smallest to largest.

Question

C++.

Write a program that reads three integers from cin and outputs them in order from smallest to largest.

Example: input of 3 8 5 should result in output of:

3 5 8

Hints:

1. You do not have to actually "sort" the values, just print them in the right order.
2. You are going to have to use nested if/else statements or && to solve this.
3. To put a space between numbers, print " ". Like: cout << a << " " << b;

Code:

#include <iostream>

using namespace std;

int main()

{

//YOUR_CODE

}

Answer 1

using namespace std;

#include <iostream>

void intSwap( int * x, int * y)

{

int iTemp;

iTemp = *y;

*y = *x;

*x = iTemp;

}

Go()

{

int num1;

int num2;

int num3;

cout << "Please input the 1st integer :>";

cin >> num1;

cout << "Please input the 2nd integer :>";

cin >> num2;

cout << "Please input the 3rd integer :>";

cin >> num3;

if (num1>num2) { intSwap(&num1,&num2); }

if (num2>num3) { intSwap(&num2,&num3); } //num3 contains the largest

if (num1>num2) { intSwap(&num1,&num2); } //sorting complete

cout << num1 << " " << num2 << " " << num3 << endl;

}

int main()

{

Go();

}
