    Thumbs down nested for loops/

    Code:
    #include<iostream>
    #include<conio.h>
    #include<iomanip>
    
    using std::cout;
    using std::cin;
    using std::endl;
    using std::setw;
    
    int main()
    {
        // declare & initialize variable/s
        
        int x,y,z,c;
        
        // print astericks
        
        for(x=1;x<=11;x++)
        {    
            cout<<'*';
            for(y=x-1;y<=9;y++)
            cout<<'*';cout<<endl;
        }
        
        cout<<"\n";
        
        for(x=0;x<=11;x++)
        {    
            cout<<'*';
            for(y-=x;y<=9;y++)
            cout<<'*';cout<<endl;
        }
        
        cout<<"\n";
        
        for(x=1;x<=11;x++)
        {    
            cout<<'*';
            for(y=1;y<=9;y++)
            cout<<'*';cout<<endl;cout<<setw(2);
        }
        
    getch();
    }
    The last for loop doesn't work if I have to print the following

    *********
    ********
    *******
    ******
    *****
    ****
    ***
    **
    *

    should it be

    ( print one whole row of * and print the next row after leaving first *)?

    Something like this ?
    Code:
    for(int x = 9; x > 0; x--)
    {
        for(int y = 0; y < x; y++)
        {
    	cout << '*';
        }
        
        cout << endl;
    }
    Just a small remark:
    In your comments you say "declare & initialize variable/s", when no initialization is done.
