Problem Solving: Printing a Rectangular Pattern

Printing a rectangular pattern

In this lesson, we’ll learn to print a rectangle using nested for loops.

Let’s say we have to print the following shape:

Height: 3
Width:  10
Symbol: -

To print the above rectangle, we will take width and height as input. In the above shape, the width is 10, the height is 3, and the symbol is '-'.

Idea

We will follow the following strategy:

• We’ll print the pattern line-by-line with a total of as many lines as the height variable. (3 lines from our example above). For this, we’ll have a for loop counting from 1 till height.
