C++ program: write a program that prompts the user to input three numbers. the program should then output the numbers in ascending order, separated by a single space.

// here is code in C++.

#include<iostream>

using namespace std;

int main()

{

// declare variables

  double num1, num2, mun3, t;

  cout << "Enter three numbers: ";

// read the three numbers

  cin >> num1 >> num2 >> mun3;

  //sort the three numbers

  if( num1>num2 )

  {

     t = num1;

     num1 = num2;

     num2 = t;}

  if( num2>mun3 ){

     t = num2;

     num2 = mun3;

     mun3 = t;}

  if( num1>num2 ){

     t = num1;

     num1 = num2;

     num2 = t;

  }

  // print the output

  cout<<"numbers in ascending order:";

  cout << num1 << " " << num2 << " " << mun3 << endl;

  return 0 ;

}

Explanation:

Declare three variables to store the input. Read the value of all three variables. If first number is greater than second, then with the help of variable "t" swap the  value of first and second.after that if second is greater than third number, swap them.In last if first number is greater than second one then swap them. This will sort the three numbers in ascending order.

Output:

Enter three numbers: 3 7 2                                                                                                

numbers in ascending order:2 3 7

sory but complete the question
