What is a flowchart?
A flowchart is a means of visually representing the flow of data through an information processing system, the operation performed within the system, and the sequence in which they are performed.
Start or end of program- a rectangle with curved edges
Computational steps or processing function of a program- a rectangle with pointed edges
Input or output operation- rectangular parallelogram
Decision making and branching- a diamond shape
Flow line- Arrows, pointing in a certain direction
With the decision making symbol (diamond) and the process symbol (rectangle), what are the rules for how many lines can enter and leave the symbol?
For a decision symbol- only one flow line should enter, but two or three flow lines exit (one for each possible answer)
For a process symbol- only one flow line should enter and exit
