To draw a rectangle of asterisks you need to think like a computer. That is, think in terms of lines and not rectangles.

These lines:

****************
*............................*

are all you need to display a rectangle. Just display them as many times as needed and in the right order.

The dots are spaces.

Also I think you need two (for) loops .....one to control the rows and the second to control the columns in which the character or white space is printed.

Actually, you could just cout each line of the rectangle and use no loops at all.

Yeeees-----but but would it be possible to react to user input specifying length and breadth using this coding method?
i.e.

std::cout<<ch<<" "<<" "<<" "<<" "<<" "<<ch;

Reacting to user input will require more code. I made the statement to liuiustrate that a rectangle does not need a loop to create it. Creating a flexible one whose size is not known until run time will require calculations and probably a loop.
