In this article, we will learn how to write a swift program to print an identity matrix. Identity matrix is a square matrix in which the main diagonal elements contain only one and the rest of the elements are 0. For example − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 0 & 0 & 0 & 0 ewline0 & 1 & 0 & 0 & 0 ewline0 & 0 & 1 & 0 & 0ewline0 & 0 & 0 & 1 & 0ewline0 & 0 & 0 & 0 & 1\end{bmatrix}}$ Algorithm Step 1 − Create a function. Step 2 − In this function, use ... Read More
What is W3C (World Wide Web Consortium)? The World Wide Web Consortium (W3C) is an international organization that develops standards for the World Wide Web (WWW or Web). It was founded in 1994 by Tim Berners-Lee, the inventor of the Web, with the goal of ensuring that the Web remains a free and open platform for communication and innovation. The W3C works to develop and promote standards that ensure the long-term growth of the Web. It is made up of member organizations, including governments, companies, and research institutions, that contribute their expertise and resources to the development of Web standards. ... Read More
In this article, we will learn how to write a swift program to multiply two matrices by passing the matrix to a function. 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. So to multiply two matrices, we multiply the mth row of the first matrix by an nth column of the second matrix and add the products. This will create an element at the mth row and nth columns of the resultant matrix. ... Read More
In this article, we will learn how to write a swift program to multiply two matrices using multi-dimensional arrays. 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 multiply two matrices, we multiply the mth row of the first matrix by an nth column of the second matrix and add the products. This will create an element at the mth row and nth columns of the resultant matrix. For example − ... Read More
In this article, we will learn how to write a swift program to initialize and print complex numbers. Complex numbers are those numbers which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. Alternatively, we can say that a complex number is a combination of both real and imaginary numbers. For example 1+2i, 1-3i, etc. In Swift, we use a struct to create complex numbers. Algorithm Step 1 − Create a structure using the struct keyword. Step 2 − In this structure, create two properties ... Read More
In this article, we will learn how to write a swift program to get the real part from the complex number. Complex numbers are those numbers 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, 2+2i, 1-3i, etc. where 2 and 1 are the real part and 2i and -3i is the imaginary part. Here we use the following methods to get the real part − Using the function Without using the function Method 1: Using the function To get the real ... Read More
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
