        cout << number << " ";
        number--;
    }

Answer 1

#include <iostream> //including the iostream library
using namespace std;    //using namespace so you dont have to type std:: e.g. std::cout<<

int main()      //main function starts here
{
    //this is where all your code goes
    
    int number;     //creating a variable number with the type integer

    cout << "Enter a number: ";     //this is outputting text to the console window

    cin >> number;                  //this gives number the value that is typed in to the console by the user

    while(number >= 1)              //while loop that checks if number is bigger than 1 if its true than the following thing will be done
    {
        cout << number << " ";      //this line is outputting the value of number and " "
        number--;                   //the value of number gets decremented by 1 until number reaches 0 than the loop-statement is false and the program ends
    }           

    
    return 0;                       
}
