In Python, there are several ways to input a string from the user. The most common method is by using the built-in function input(). This function allows the user to enter a string, which is then stored as a variable for use in the program. ExampleHere's an example of how to input a string from the user in Python −# Define a variable to store the input name = input("Please enter your name: ") # Print the input print("Hello, " + name + "! Good to see you.") OutputThe above code generates the following output for us −Please enter your name: ... Read More
In this tutorial, we will learn to count JavaScript array objects. The array is the data structure containing the strings, numbers, objects, etc., in JavaScript. The object is the one kind of entity that contains properties and methods related to it. We can access the object's properties and invoke the object method using the object's references. Generally, To find the array length, we can use the array.length() method and it returns the total number of elements that the array includes. But what if we need to count only object elements? Here, this tutorial has various approaches to counting the total ... Read More
We can type Enter/Return key in Selenium. We shall use the sendKeys method and pass Keys. ENTER as an argument to the method. Also, we can use pass Keys. RETURN as an argument to the sendKeys method for the same purpose.To use the Keys class, we have to incorporate import org.openqa.selenium.Keys to the code. Let us type Enter/Return after inputting text within the below edit box.Exampleimport org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.By; import org.openqa.selenium.Keys; public class TypeEnter{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ...

Suppose we have a complex number class with real and imaginary part. We shall have to overload the addition (+) operator to add two complex number. We also have to define a function to return complex number in proper representation.So, if the input is like c1 = 8 - 5i, c2 = 2 + 3i, then the output will be 10 - 2i.To solve this, we will follow these steps −Overload the + operator and take another complex number c2 as argumentdefine a complex number called ret whose real and imag are 0real of ret := own real + real ...

Intel 8051 is an 8-bit microcontroller. It has many powerful instructions and IO accessing techniques. In this section, we will see one of the simplest program using 8051.Here we will add two8-bit numbers using this microcontroller. The register A(Accumulator) is used as one operand in the operations. There are seven registers R0 – R7 in different register banks. We can use any of them as the second operand.We are taking two number 5FH and D8H at location 20H and 21H, After adding them, the result will be stored at location 30H and 31H. AddressValue...20H5FH21HD8H...30H00H31H00H...ProgramMOVR0, #20H;set source address 20H to R0 ... Read More
Cache memory, often known as cache, is a different memory system in a computer that stores frequently used data and instructions for a short period. While loading a website, the browser we are using will automatically cache some resources, such as images, scripts, and stylesheets, to be utilized again when the page is reloaded. This can shorten the time it takes for a website to load not only that but also it helps to lower the amount of data that has to be sent over the network. But this cache memory stored by the browser also has some disadvantages. If ... Read More
Pipelining defines the temporal overlapping of processing. Pipelines are emptiness greater than assembly lines in computing that can be used either for instruction processing or, in a more general method, for executing any complex operations. It can be used efficiently only for a sequence of the same task, much similar to assembly lines.A basic pipeline processes a sequence of tasks, including instructions, as per the following principle of operation −Each task is subdivided into multiple successive subtasks as shown in the figure. For instance, the execution of register-register instructions can be broken down into instruction fetch, decode, execute, and writeback.A ... Read More
A wide area network (WAN) is a computer network that covers a large geographical area comprising a region, a country, a continent or even the whole world. WAN includes the technologies to transmit data, image, audio and video information over long distances and among different LANs and MANs.The distinguishing features of WAN areWANs have a large capacity, connecting a large number of computers over a large area, and are inherently scalable.They facilitate the sharing of regional resources.They provide uplinks for connecting LANs and MANs to the Internet.Communication links are provided by public carriers like telephone networks, network providers, cable systems, ...

The aim of this article is to implement a program C++ program to check if all rows of a matrix are circular rotations of each other. Here is a small glimpse on what a matrix exactly is. The rectangular array of symbols or numbers organized in rows and columns is known as a matrix. A matrix can be of many distinct types, including row, column, horizontal, vertical, square, diagonal, identity, equal, and singular. Addition, subtraction, as well as multiplication are the three fundamental matrix operations. The goal is to determine whether all rows of a matrix of size n*n ... Read More
The aim of this article is to implement a program C Program To Write Your Own atoi(). Before we begin, let us take a deeper understanding of what an atoi() function is all about. This will help in writing the program as well as understanding the concepts pretty much easier. To the ones who are not much aware of what an atoi() function is. Here you go. The atoi() function changes a string of elements into an integer value. The string that is entered is a string of characters that has the potential to become a numeric value of the ... Read More
