Flow Chart Basic

1. What is a flowchart?
A flow chart is a graphical or symbolic representation of a process which will lead to getting the solution of the problem. Each step in the process is represented by a different symbol and contains a short description of the process step. The flow chart symbols are linked together with arrows showing the process flow direction.



2. Describe the basic flowchart symbols for;

• Start or end of the program :

basically a rounded edged rectangle.

• Computational steps or processing function of a program:

The symbol is basically a normal rectangle

• Input or output operation:

The symbol for this is a parrallelogram

• Decision making and branching:

 The symbol for this is a diamond

• Flow line:

The symbol depending on the direction of flow it is an arrow pointing in that direction

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 of the process symbol(rectangle) and only one flow can enter a decision symbol,but two ore three flowlines,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.
