Pseudocode General

Pseudocode is a brief explanation of code in plain English.

Writing pseudocode is a good way to map out your ideas for a program before actually writing the real code. It can help you think about the function decomposition, the top down design, and the structure of a program.

Here are some examples of pseudocode:

1: Pseudocode to put down 10 tennis balls

repeat 10 times:
    put ball

2: Pseudocode to draw a tower on every avenue in a Karel world.

while front is clear:
    build tower
    move
build last tower

then, you can also pseudocode the build tower part like this:

build tower:
    turn left
    repeat 3 times:
        put ball and move
    turn around
    move down
    turn left

Pseudocode is easier to write, so you can get an understanding of your strategy before diving into a tricky program.
