#include <iostream>

using std::cin; using std::cout; using std::endl;

int main(){

  // inputs the numbers
  cout << "Enter three numbers: ";
  int x, y, z;
  cin >> x >> y >> z;

  int tmp;

  // orders x and y
  if (x > y){
    tmp = x;
    x = y;
    y = tmp;
  }

  // orders y and z
  if (y > z){
    tmp = y;
    y = z;
    z = tmp;
  }

  // outputs the sorted numbers
  cout << "The sorted numbers are: ";
  cout << x << " " << y << " " << z << endl;

Can anyone help complete?

Answer 1

Completed the code:

#include <iostream>

using namespace std;

int main(){

// inputs the numbers
cout << "Enter three numbers: ";
int x, y, z;
cin >> x >> y >> z;

int tmp;

// orders x and y
if (x > z){
tmp = x;
x = z;
z = tmp;
}

// orders y and z
if (x > y){
tmp = y;
x = y;
y = tmp;
}
//Now the smallest element is the first one. Just check the 2-nd and 3-rd
if (y > z){
tmp = y;
y = z;
z = tmp;
}

// outputs the sorted numbers
cout << "The sorted numbers are: ";
cout << x << " " << y << " " << z << endl;
}

Output:
