Flow chart to compute the average of N number?

Answer 1

The flowchart in deriving the sum of two numbers and its average, you may follow the steps provided below:

1. Draw the start symbol then a flow line connecting to item #2
2. Draw the init box for the syntax: set variable_Sum=0, variable_Ave=0, Variable_A=0, Variable_B=0 then a flow line connecting to item #3
3. Draw the first input box and write variable_A then a flow line connecting to item #4
4. Draw the decision box for 'Is variable_A not numeric?'. if yes, draw a flow line connecting to item#3 else draw a flow line connecting to item #5
   
5. Draw the second input box and write variable_B then a flow line connecting to item #6
6. Draw the decision box for 'Is variable_B not numeric?'. if yes, draw a flow line connecting to item#5 else draw a flow line connecting to item #7
7. Draw the first process box for the syntax: compute variable_Sum=variable_A + variable_B then a flow line connecting to item #8
8. Draw the second process box for the syntax: compute variable_Ave=variable_sum / 2 then a flow line connecting to item #9
9. Draw the output box and write variable_Sum, variable_Ave then a flow line connecting to item #10
   
10. Draw the end symbol.

Where:
variable_A contains the first number, variable_B contains the second number, variable_Sum contains the sum of variable_A and variable_B, and variable_Ave contains the average of variable_Sum.

The last time I checked the LETTER "N" is not a number
