1.Algorithm:
Step 1: Initialize the variable to store the data
Step 2: Display the Welcome message
Step 3: Display the Menu
Step 4: Get the menu option from the user
Step 5: If the User Selects Setup Cost Per KM option perform step 6 and 7 else move to Step 10
Step 6: Get the costs per km for a package to be sent for 100KM or less distance from the User
Step 7: Get the costs per km for a package to be sent for over 100KM distance from the User
Step 8: Display the details entered by the user
Step 9: Go to Step 3
Step 10: If the User Selects Enter Parcel option perform step 11 to 17 else move to Step 18
Step 11: Get the receiver name of the package from the User
Step 12: Get the weight of the package from the User
Step 13: Get whether the insurance is required for the package from the User
Step 14: Get the number of KMs the package wants to travel from the User
Step 15: Display the details entered by the user
Step 16: Compute the delivery date of the package
Step 17: Go to Step 3
Step 17: If the User Selects Display Parcel Delivery Costs option perform step 18 to 23 else move to Step 24
Step 18: Compute the transportation cost by multiplying the distance and its corresponding cost
Step 19: Determine the insurance cost if the insurance is required for the package
Step 20: Compute the total cost i.e. transportation cost + insurance cost
Step 21: Display the cost details
Step 22: Display the delivery date of the package
Step 23: Go to Step 3
Step 24: If the user select the Exit System option perform step 25 else go to step 27
Step 25: Display the Exit message to the user
Step 26: Terminate the program execution
Step 27: If the user enters none of the option; Display the message of invalid choice and Go to Step 3
