    Hey guys ,I'm a beginner of C++,

    I'm stuck on a perticular problem in which a user is asked to input a number less than 10.
    For instance 8.

    then the output will be like 1 2 3 4 5 6 7 8 6 5 4 3 2 1 get it? it will count till the input number and then count back to one.


    The main issue about this problem is that everything has to be done in a If/esingle for-loop.lf/else statements are not allowed and using any extra variable outside the loop is also not allowed.

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main(){
        int i,number=11;
        while (number>=10){
            cout<<"enter a number <10:";
            cin>>number;
        }
        for (i=-number+1;i<=number-1;i++){
            cout<<(number-abs(i))<<" ";
        }
        return 0;
    }
