What is Webmail? Webmail is a type of email service that allows users to access and manage their email messages through a web browser. Instead of using a dedicated email client like Microsoft Outlook or Apple Mail, users can log in to their email account using a web-based interface and perform tasks like reading and sending email, organizing messages into folders, and managing their contacts. Webmail is convenient because it can be accessed from any device with an internet connection and a web browser, without the need to install any software. This makes it particularly useful for users who need ... Read More
In this article, we will learn how to write a swift program to get the numerator from a rational number. A rational number is a number which represents in the form of n/m where m is not equal to zero. Here n is known as the numerator and m is known as the denominator. For example, 7/9, 13/23, etc. Here, 7 and 13 are numerators whereas 9 and 23 are denominators. Algorithm Step 1 − Create a structure to create a rational number. Step 2 − In this structure, create two properties of integer type to store the numerator and ... Read More
In this article, we will learn how to write a swift program to get the imaginary part of the given complex number. Complex numbers are those number which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. For example: 1+2i, 1-3i, etc. Here we use the following methods to get imaginary part − Using function Without using function Method 1: Using function To get the imaginary part of the complex number we create a function which takes struct object as a parameter and return the ...

What is POP3 (Post Office Protocol 3)? Post Office Protocol version 3 (POP3) is a standard protocol used by email clients to retrieve email messages from a mail server. It is a simple, text-based protocol that allows a client to connect to a server, retrieve email messages, and mark them as read or unread. POP3 works by establishing a connection between the email client and the mail server. The client sends a request to the server to retrieve email messages, and the server responds with a list of available messages. The client can then choose which messages to download and ... Read More
In this article, we will learn how to write a swift program to get the denominator from the rational number. A rational number is a number, which represents in the form of n/m where m is not equal to zero. Here n is known as the numerator and m is known as the denominator. For example, 2/3, 11/19, etc. Here, 2 and 11 are numerators whereas 3 and 19 are denominators. Algorithm Step 1 − Create a structure to create a rational number. Step 2 − In this structure, create two properties of integer type to store the numerator and ... Read More
In this article, we will learn how to write a swift program to copy all the elements of one array to another array. Swift doesn’t provide a direct method to copy the elements of one array to another but we can do this using the following methods − Using map(_:) method Using = operator Using append(contentsOf:) method Method 1: Using map(_:) method The map(_:) method is used to return an array that contains the result of mapping the given closure over the specified sequence’s elements. Syntax func map(_mclosure:(Self.Element) throws - >T)rethrows [T] Here, mclouser is a mapping ... Read More
In this article, we will learn how to write a swift program to check if a number is a spy number or not. A spy number is a number in which the sum of the digits of the given number is equal to the product of the digits of the given number. For example − Number = 123 Sum = 1 + 2 + 3 = 6 Product = 1 * 2 * 3 = 6 Hence 123 is a spy number because sum = product Number = 23 Sum = 2 + 3 = 5 Product = 2 * ... Read More
In this article, we will learn how to write a swift program to check if a given square matrix is the identity matrix. The identity matrix is an MxM square matrix in which the main diagonal consists of ones and other elements are all zero. For example − $\mathrm{M\:=\:\begin{bmatrix}1 & 0 & 0 & 0ewline0 & 1 & 0 & 0 ewline0 & 0 & 1 & 0 ewline0 & 0 & 0 & 1\end{bmatrix}}$ Whereas a square matrix is a matrix in which the number of rows is equal to number of columns and it may or may not ...

In this article, we will learn how to write a swift program to add two matrices using a multi-dimensional array. A matrix is a mathematical structure in which the elements are present in rows and columns format. For example, the first element is present at the a00 location, the second at a01, and so on. Therefore, to add two matrices we are going to use + operator to add the elements of two matrices like a00 + b00 and then store the sum into a new matrix. For example: Matrix 1 − $\mathrm{\begin{bmatrix}2 & 3 & 4 ewline5 & 2 ... Read More
Generally, when we need to edit multiple cells very frequently, we will be selecting the cells using the ctrl command and clicking on delete, but sometimes it can be a problem when we select different cells or when we miss selecting some cells. We can solve this problem by following the process mentioned in this article. This article will help you understand how we can apply a button to clear specific cells in Excel. This process has two parts: creating a button and assigning a macro to the button. Applying a Button to Clear Specific Cells in Excel Here we ... Read More
