Mention the tools required to develop iOS applications
In this tutorial, we are going to study about different types of tools required to develop iOS applications. As we already know, there are approximately 1 billion iPhone users. Thus, Apple always provides a hassle−free environment for developers who want to build applications for iPhone, iPad, MacBook, and Apple Watch. Apple has built a strong ecosystem for developers so they can focus on writing code and building apps. Today, we will see what tools we need to develop applications on the Apple platform. Xcode This is an editor or IDE to write code for building apps. Apple released the ...
Read MoreName Some Advantages of Using Swift
This article will explain to you the advantages of using the Swift programming language. Introduction of the Swift language Swift is a clean and concise programming language that is growing fast and becoming increasingly popular. Swift was initially used for iOS development but has become very popular for many other things like macOS, watchOS, and server-side development. Apple introduced the Swift language as an open-source programming language as a replacement for Objective−C, C, and C++. The Swift language was created in 2014 and released publicly in 2015 by Apple Inc. We can say Swift is a modern programming language like ...
Read MoreExplain the difference between let and var in Swift
This article will explain the difference between let and var in the Swift language. Most of the time, we deal with different data types in any programming language. However, we need to identify values by name. These names are called variables. Like C, Swift uses variables to store and refer to values by an identifying name. Swift also makes extensive use of variables whose values can’t be changed. These are known as constants. They are more powerful than constants in C. Constants are used throughout Swift to make code safer and clearer in intent. This is because you work with ...
Read MoreWhat is plist in iOS?
In this tutorial, we will talk about how we can use the plist in the application to store information. Let’s first understand what is plist. What is plist? The plist file is also called the property list and is used by operating systems (e.g. iOS) and users. The information is stored in a key-value format similar to a dictionary. A plist file can contain different types of values like strings, arrays, dictionaries, booleans, dates, data, and numbers, such as integers. Most of these types correspond to native Swift types, such as Array and Bool. You can also store nested arrays ...
Read MoreGolang Program to convert a number into a rational number
In this tutorial we will see how to convert a number into a rational number using Go programming language. A rational number is a type of real number, which is in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number. Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on. Syntax funcNewRat(a, b int64) *Rat NewRat creates a new Rat with numerator a and denominator b Syntax for Scanln: Func Scanln(a…interface{}) (n int, err error) Package math/big implements arbitrary-precision arithmetic (big numbers). ...
Read MoreC++ Program to calculate the logarithm gamma of the given number
The gamma function is described as an extension of the factorial of every given number in mathematics. The factorial, on the other hand, can only be defined for real numbers, hence the gamma function exceeds to calculate the factorial on all complex values other than negative integers. It is represented by − $$\mathrm{\Gamma \left ( x \right )=\left ( x-1 \right )!}$$ The gamma function grows quickly for higher values; hence, applying logarithm to the gamma will greatly slow it down. The natural logarithm gamma of a particular number is another name for it. In this article, we will see ...
Read MoreC++ Program to calculate the logarithm of a given number based on a given base
In almost any modern programming languages, we find the few logarithm functions like natural logs, log with base 2, log with base 10 etc. But sometimes we need to calculate logarithm with different base which are not available in the given library functions. To achieve this goal we can use simple logarithmic formula. In this article we will see how to calculate logarithm values with a given number and a given base in C++. Formula to calculate logarithm with given base Let we have taken a number x, and its base is k which is also given. The ...
Read MoreGolang Program to extract the last two digits from the given year
In this tutorial we will discuss how to write a GO program to extract the last two digits of a given year. This program takes any year as input and prints its last two digits. You need to extract the last two digits from a given year, by using the modulus operation. Modulus Operation The % operator is the modulus operator, which returns the remainder rather than the quotient after division. This is useful for finding numbers that are multiples of the same number. As the name suggests where there is an execution to be operated required to deal with ...
Read MoreSwift Program to Convert Char type variables to Int
This tutorial will discuss how to write swift program to convert char type variable to int. Swift support various datatypes and character and integers are one of them. Character represent single-character string like, “2”, “a”, “l”, etc. Whereas Integer represent numeric values like 2, 3, 45, 6, etc. To convert char type variable into Int type we can use any of the following method. Method 1 - Using whole Number Value Property We can convert char type variable into Int type using whole Number Value property. This property will convert character into number value if the character represent a ...
Read MoreSwift Program to Calculate Cube Sum of First n Natural Numbers
This tutorial will discuss how to write swift program to calculate cube sum of first n natural numbers. Natural numbers are those number which include all the positive number starting from 0 to infinite for example, 1, 2, 3, 4, ……n. Now we find the cube sum of first n natural numbers: 1+23+33+43 = 1 + 8 + 27 + 64 = 100. Below is a demonstration of the same − Input Suppose our given input is − Num = 5 Output The desired output would be − Cube Sum of first 5 numbers are 225. Algorithm Following ...
