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 MoreHow To Check Whether a Number is Tech Number or Not in Java?
A number is said to be a tech number, when an even digit number is divided into exactly two parts and the square value of the sum of those two numbers is equal to the original number. For more clarification, we take a number which has even digits. After that, divide it into two parts and add two parts. After getting the sum value, we calculate the square of it. Now we compare both the calculated square value and the original/input number. If both are same then we can say that the input number is a tech number otherwise ...
Read MoreHow To Check Whether a Number is Tcefrep Number or Not in Java?
A number is said to be a Tcefrep number, if the reverse of that number is equal to the sum of the proper divisors of the original number. For more clarification, we find the sum of the divisors of a number and find the reverse of the original number. If both the sum value and the reverse of the given number are the same then we can say that the given number is a Tcefrep number. Some examples of Tcefrep numbers are: 6, 498906, 20671542 ... etc. In this article, we will see how to check if a ...
Read MoreHow To Check Whether a Number is Strontio Number or Not in Java?
A number is said to be a Strontio number, if we multiply 2 with a four-digit number then in the resultant number the tens place and hundreds place digits are the same. In simple terms, Strontio numbers are basically four-digit numbers. When we multiply 2 with it, it results in a number whose tens place and hundred places are exactly the same. Some examples of Strontio numbers are- 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, 1001 ... etc. In this article, we will see how to check if a number is a strontio number by using Java ...
Read MoreHow To Check Whether a Number is Pointer Prime Number or Not in Java?
A number is said to be a pointer prime number, if the sum of the product value of digits and the original prime number results in the next prime number. For more clarification, we take a prime number and multiply the digits with each other and add that multiplication value with the original number. After that if we get another prime number which is next to the original prime number. Then we can say that the number is a pointer prime number. Some examples of pointer prime numbers are: 23, 61, 1123, 1231 ... etc. In this article, ...
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 ...
