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.
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

To write an algorithm, pseudocode, and draw a flowchart to read an integer value from the keyboard and display a message indicating if the number is odd or even, you can follow these steps:
Algorithm:
1. Start
2. Read the integer value from the keyboard
3. Divide the input value by 2
4. Check if the remainder is equal to 0
5. If the remainder is 0, display a message "Number is even"
6. If the remainder is not 0, display a message "Number is odd"
7. End
Pseudocode:
1. Start
2. Prompt the user to enter an integer value
3. Read the input value and assign it to a variable (let's say 'num')
4. If num % 2 is equal to 0, then
- Display "Number is even"
Else
- Display "Number is odd"
5. End

Note: In the flowchart, the diamond shape represents a decision-making point, and the rectangular shapes represent processes or actions.
