Flowchart symbols and logic

FLOWCHART BASICS

The site below is excellent for understanding flowchart symbols and logic. (This will be an excellent resource for developing the flowchart required in the assessment!). For today read through the tutorial and post about the following.

1. What is a flow chart? 

Is a means of visually displaying the flow of data 

2. Describe the basic flowchart symbols for: 

• Start or end of the program:

• Computational steps of processing function of a program:

• Input or output operation:

• Decision making and branching: 

• Flow line:

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 enter and exit from a process symbol 

Only one flow line should enter a decision symbol, but two or three flow lines (one for each possible answer) 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.
