If a programming language can't let you making choices, it is nearly useless. Control flow statements, are very important in a general purpose programming language like C++ because they let you making decisions inside your program.

The following teaching aid help you understand more about the control flow statements: if...then...else, while..., do...while. it convert the program you typed to a flow chart and let you run the program using the flow chart.

Type the code segment you want to convert to flow chart in the input code window and press the "Convert!" button. Then, the main window will display the corresponding flow chart. Now, you can press the "Run" button to run the program on the flow chart.

Notes: the program now only support the control flow statements: if...then...else, while...., do...while. Function, variable and class declaration are not supported.
