Answer:
customers += newCustomer;
Explanation:
The operator += expands into + and assignment. The assignment is not overloaded so the required code is
customers += newCustomer;
This expands into
customers = customers + newCustomer;
The overloaded + operator is called for the right expression. This returns a `CustomerList`, which is then assigned through the = operator to `customers`.
Answer:
Option C i.e., RIPEMD is the correct option for the following question.
Explanation:
Because RIPEMD is the algorithm that is used for the hash primary design characteristic which has two independent and unlike parallel chains of the calculation and computation and the outputs of which are then linked to the process at the end. It is also used for the safe process of replacing the 128-bit hash method.
Other options are wrong because these are not related to the following statement.
Answer:
1. get the absolute path to the file
2. load the file as a table (dataframe in python)
3. to insert a row;
- create a dataframe of the same field type
- concatenate the new dataframe horizontally with the same dataframe
4. to delete a row, select and drop the row where the 'Number' field matches a value.
5. to update the values in row, use the number field as a key to replace the existing values.
6. print of save to a variable the rows where the number field matches a given value.
Explanation:
Follow the report template to create a report for the algorithm.
The algorithm gets the absolute path to the file and loads the file as a tabular file from there the data can be queried without accessing the main file. The insert algorithm creates a new dataframe and appends it to the main dataframe.
The delete, update and retrieve all use the same subalgorithm, getting the rows with the number field as the key value.
Answer: C) Access panel
Explanation:
During the installation process, access panel is used remove by the technician for installation extra 4 GB memory in the laptop. As, window access panel is useful to change the window settings.
We need to access the panel in the laptop to add extra 4 GB memory in the laptop as, the access panel contain the memory banks in the system. Then, open that particular panel for upgrade the memory in the laptop and also remove the unnecessary memory.
Well a printer takes data and puts it on a piece of paper so it would be an output device
