Write a shell script to determine whether the year entered is a leap year or not?



echo “enter  any year ”
read num
if [ `expr $num % 100` -eq 0 ]
then
if [ `ex pr $num % 400` -eq 0 ]
then
echo "Leap year"
else
echo "Not a leap year"
fi
else
if [ `expr $num % 4` -eq 0 ]
then
echo "Leap year "
else
echo "Not a leap year"
fi
fi





OUTPUT :

enter any year
1999
Not a leap year

enter any year

Traversing of elements program with algorithm and Flowchart

Image
ALGORITHM VARIABLES: §   i:      loop counter of array. §   A:    array name. §   LB: lower bound. §   UB: upper bound. ALGORITHM: STEP 1:         set i =LB STEP 2:         repeat steps 3 & 4                            While i<=UB STEP 3:         apply process to A[i] STEP 4:         i = i+1            STEP 5:         exit EXPLANATION: §   To traverse the elements of the array, firstly set the loop counter ‘i’ equal to last element of the array called the LOWER BOUND. §   Now, repeat step 3 & 4 for accessing all the elements of the array until loop counter ‘i’ is not less than or equal first element of array. §   Now, after checking the above condition, the whole process will repeat for all the elements of array. §   After applying process upon a[i], increment the loop counter by 1, until the condition is not satisfied.
