We can repeat a statement or block of statements with a for
loop. The simplest for loops take the following form:
The control variable i takes every value 0,1,2..9 in turn. We can use the value of i inside the loop if required.
Consider the neighbouring state Qatar.
- 9 pillars, each pillar is 17 pixels below the previous.
- The five coordinates of the top pillar are (0,0) (84,0) (125,9) (84,17), (0,17)
- Use RGB(128,0,0) for the less jaunty red.
Flag of Qatar
The need for a loop becomes even more obvious for this flag.
