Danish Flag

This is a pair exercise and must be competed in your tutorial or lab with your partner.

In this task, you will create a program called danishFlag.c which will read in a size and display a Danish Flag of that size using the following algorithm and the # character.

The Danish Flag is made up of 6 blocks. It is 3 blocks wide, and 2 blocks high. To display it using empty spaces and the character #, we will read in a value called size. Each block will be 3 times size wide, and 2 times size high.

In the top left block, the right column and bottom row will be empty spaces.
In the top middle block, the left column and bottom row will be empty spaces.
In the top right block, the bottom row will be empty spaces.
In the bottom left block, the right column and top row will be empty spaces.
In the bottom middle block, the left column and top row will be empty spaces.
In the bottom left block, the top row will be empty spaces.
Every other position will be the # character.

See the diagram below for details.

To run some simple automated tests:

$ 1511 autotest danishFlag

To run Styl-o-matic:

$ 1511 stylomatic danishFlag.c
Looks good!
