Draw a flowchart to find the sum and the average of two numbers?

Answer 1

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

# Draw the start symbol then a flow line connecting to item #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 # Draw the first input box and write variable_A then a flow line connecting to item #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

# Draw the second input box and write variable_B then a flow line connecting to item #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 # Draw the first process box for the syntax: compute variable_Sum=variable_A + variable_B then a flow line connecting to item #8 # Draw the second process box for the syntax: compute variable_Ave=variable_sum / 2 then a flow line connecting to item #9 # Draw the output box and write variable_Sum, variable_Ave then a flow line connecting to item #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.
