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.
