Question

Write an algorithm and draw a flowchart to input year and check whether it is leap year or not. (A year is leap year if year%400=0
Please help guys ​

Answer 1

Answer:

Algorithm

Algorithm of this program is −

START

  Step 1 → Take integer variable year

  Step 2 → Assign value to the variable

  Step 3 → Check if year is divisible by 4 but not 100, DISPLAY "leap year"

  Step 4 → Check if year is divisible by 400, DISPLAY "leap year"

  Step 5 → Otherwise, DISPLAY "not leap year"

STOP

Flow Diagram

We can draw a flow diagram for this program as given below −

Answer 2

Leap Year is divisible by 4 or 400 and is not to be divisible by 100.

Explanation:

• The condition to verify if the given year is a leap year or not the following condition must be true:

        let 'x' be the year.

1. x should be divisible by 4 or 400.
2. x should necessarily not be divisible by 100.

Following shows the true condition for leap year:-

if((x % 400==0 )||(x%4==0 && x%100!=0))

{

      //Statements

}

else

{

      //Statements
