Write a C++ program to arrange 10 numbers in ascending order

Exercise 2)
Write a C++ program and call it sortcheck.cpp which receives 10 numbers from input and checks whether these numbers are in ascending order or not. You are not allowed to use arrays. You should not define more than three variables.

e.g    Welcome to the program written by Your Name:
Please enter 10 Numbers: 12 17 23 197 246 356 790 876 909 987
Fine, numbers are in ascending order.

Solution-

#include<iostream>
#include<cmath>

using namespace std;

int main()

    char redo;
    double a,b,d;
    
 do
    {

//--------Printing my name on screen----------------    
    cout<<"Welcome to the  program  written by Your Name"<<endl;
    cout<<"***************************************************************"<<endl;
    cout<<endl<<endl<<endl;
    //----receiving the variables from input--------------         
    cout<<" Please enter the ten values to know the result";
    cout<<endl;
    cin>>a>>b;
// if condition is introduced to check the sort sequence
         if(a<b)
        {
               
         a=b;
         d=d+1;

//once again the the place at b is empty so required new no. fo variable b
