Question

how to write algorithm and pseudocode and how to draw flowchart to read an integer value from the key board and display a message indicating if the number is odd or result.

Answer 1

Algorithm:

Step 1: Start
Step 2: Declare integer variable num
Step 3: Read input from keyboard and store it in variable num
Step 4: Check if num modulo 2 equals to 0
Step 5: If it is true, display a message "The number is even"
Step 6: If it is false, display a message "The number is odd"
Step 7: Stop

Pseudocode:

BEGIN
DECLARE num as integer
READ num from keyboard
IF num modulo 2 is 0 THEN
DISPLAY "The number is even"
ELSE
DISPLAY "The number is odd"
ENDIF
END
