Flowcharts

1. What is a flowchart?

A flowchart is a means of visually presenting the flow of data through an information processing system.

2. Describe the basic flowchart symbols for;

•  Start or end of the program a rectangle with curves on the corner
• Computational steps or processing function of a programa rectangle with curves on its edges
• Input or output operation a rectangular box
• Decision making and branching a rectangular box
• Flow line a diamond 

3. With the decision making symbol (diamond) and the process symbol (rectangle), what are the rules for how many lines may enter and leave the symbol.
5. In a rectangle one line must enter and one must leave. Whereas in a diamond one enters and two come out.
6. Study the sample flowcharts then create a flowchart for a coin toss where heads means Mary pays for the pizza and Tales means Bill pays.

The sum is a variable and so is N in the example
