Problem

Design a flowchart that finds and displays the larger of the two numbers provided by the user. Let’s assume the numbers are x and y. The flowchart prompts the user for the values x and y.

IPO chart

Consider modeling an IPO chart for the flowchart before the flowchart design. Think about the input to the flowchart, processing statements, and the output of the flowchart. IPO chart is a handy tool to visualize in a tabular format.

Pseudocode

START
DECLARE x,y

INPUT x
INPUT y
IF x != y THEN
         IF x > y THEN
             DISPLAY "The larger of the two numbers " + x + " 
 and " + y + " is " + x
         ELSE
             DISPLAY "The larger of the two numbers " + x + " 
 and " + y + " is " + y
END IF
ELSE
       DISPLAY "Both the numbers are equal"
END IF
END

Flowchart

We will prompt the user to enter two numbers x and y.

We will check if the numbers are equal. If not then we will check for larger of the two numbers.

Sample Output

Let’s run the flowchart with sample test cases to verify that it’s working as intended. If you find that the flowchart is not working as intended in the testing, we may need to verify and debug the flowchart.
