Flowcharts tutorial
Click Next to step through the flowchart. A red dot shows the current step to execute. (This is a Java Applet, for security, it has a low priority on your machine, sometimes you have to click next twice before it continues.) Values of variables are shown on the left.
When the flowchart indicates Input, type a value in the blue input box, then click OK. When the flowchart indicates Print, the value will be displayed: click OK to continue.
Click Start to restart the algorithm at the beginning. Run the flowchart several times with different values to see how the algorithm works.
Arrays: If there is an array of numbers, they will be given new, random values each time you click Start. Subroutines: If there is a subroutine, there will be a flashing blue dot at the calling procedure.
Pass by reference: If a subroutine has arguments that are passed by reference, they will be indicated with a circle instead of a square for the value. When they receive a reference variable, a line will connect the argument name with the reference variable.
