It is a means of visually presenting the flow of data through an information system, the operations performed within it and the sequence at when they are performed.
2. Describe the basic flowchart symbols for;
• Start or end of the program- a rectangular shape with rounded corners.
• Computational steps or processing function of a program- rectangular shape with sharp corners
• Input or output operation- parallelogram
• Decision making and branching- diamond/kite shape
• Flow line- arrows pointing the direction of the flow.
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.
Only one flow line should come out from a precess symbol, while one flow line can enter a decision symbol although two or three lines should leave the decision symbol.
4. 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.
