This will format the code and add the correct indentations wherever required.Before Auto-FormatAfter Auto-Format
In order to change the baud rate of the Serial Monitor, go to Tools -> Serial Monitor (or press Ctrl+Shift+M alternatively).Make sure you have a board connected to your PC/Laptop, or the Serial Monitor won't open. Also, make sure that the Port corresponds to the connected board.Once the Serial Monitor is open, you can see the baud rate dropdown at the bottom and select the required baud rate from there.
In this post, we will understand the difference between Applet and Application.ApplicationThey are similar to Java programs.They can be executed independently without using web browser.It requires a ’main’ function for it to be executed.Java applications have full access to local file system and network.They can access all kinds of resources that are available to the system.They can execute the programs with the help of the local system.An application program is required when a task needs to be directly performed for the user.AppletsThey are small Java programs.They have been designed to be included with HTML documents.They need Java enabled web browser ...

Problem Statement: Use boto3 library in Python to get details of all classifiers present in AWS Glue Data catalog. For example, get the details of all classifier from user’s account.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − There is no parameter.Step 3 − Create an AWS session using boto3 library. Make sure region_name is mentioned in default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4 − Create an AWS client for glue.Step 5 − Call get_classifiers.Step 6 − It will fetch details of ...

Problem Statement − Use boto3 library in Python to check statuses of all runs of a given job.Example − Get the status of all runs of a glue job named as ‘run_s3_file_job’.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − job_name is the mandatory parameters. The function will fetch the details of a given job_name.Step 3 − Create an AWS session using boto3 library. Make sure region_name is mentioned in default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4 − Create an AWS client ... Read More
In this post, we will understand the difference between Link and Association.LinkIt can be understood as the physical connection between objects.It helps tell about the relationship among objects.It is represented using line segment between objects.They can’t be referenced.It is used in UML designs.AssociationIt is a specification about the collection of links.The connections are related to classes.It is a general relationship between classes.They are implemented using programming languages as a reference model.It shows connections between classes using line segments.It is used in UML designs.
In this post, we will understand the difference between Friend function and Friend class.Friend FunctionIt is usually used with operator overloading operation.It is used with the ‘friend’ keyword.It helps give a non-member function the access to the private members of the class.It has to be declared before it is used.It is used to access private and protected members of the class.It can be a global function or a function in another class.Exampleclass Node { private: int val; Node* next; // Other members of Node Class // friend int LinkedList::search(); // Only search method ...

In this post, we will understand the difference between server-side scripting and client-side scripting.Server-side ScriptingIt helps work with the back end.It doesn’t depend on the client.It runs on the web server.It helps provide a response to every request that comes in from the user/client.This is not visible to the client side of the application.It requires the interaction with the server for the data to be process.Server side scripting requires languages such as PHP, ASP.net, ColdFusion, Python, Ruby on Rails.It is considered to be a secure way of working with applications.It can be used to customize web pages.It can also be ...

In this post, we will understand the difference between GET and POST methods in HTML.GET MethodThe parameters are placed inside the URL.Its main goal is to retrieve the data/documents present inside it.It has the ability to bookmark the results of the query.It is vulnerable, and not secure enough.This is because the data and credentials are present as plain text.It can be seen by anyone.The data constraint is that only ASCII characters are allowed.It can be up to 2000 characters only.It is also said to keep the length of the data to a minimum value.Data can be cached when GET method ...

In this post, we will understand the difference between linear queue and circular queue −Linear QueueIt is a linear data structure, which data is arranged in a linear pattern.Operations such as insertion and deletion are done from rear and front respectively.It requires more memory, since data is stored in a linear fashion.The element that is added to a linear queue at first, is the element that gets deleted first.It follows FIFO, i.e first in first out.The element that is inserted first is the element that is deleted first as well.It is not as efficient as a circular queue structure.Circular QueueThe ...
