Swift program to find the reverse of a given number using recursion
This tutorial will discuss how to write swift program to find the reverse of a given number using recursion. Reversing a number is a process in which the position of the digits of a number is interchanged to reverse their order. To find the reverse of the number we use recursive approach. Recursive approach is an approach in which a function call itself to complete the specified task. Below is a demonstration of the same − Input Suppose our given input is − MyVal = 278938 Output The desired output would be − Reverse number = 839872 Method ...
Read MoreSwift program to display prime numbers between intervals using function
This tutorial will discuss how to write swift program to display prime numbers between intervals using function. Prime numbers are those numbers that are greater than 1 and has exactly two factors that is 1 and the number itself. For example, 7 is the prime number because it has only two factors that are 1 and 7. Below is a demonstration of the same − Input Suppose our given input is − Lower Interval = 18 Upper Interval = 42 Output The desired output would be − Prime numbers between 18 to 42 are 19 23 29 31 37 ...
Read MoreSwift program to convert double type variable to string
This tutorial will discuss how to write swift program to convert double type variable to int. Swift support various datatypes and double and string are one of them. String is an ordered collection of characters. For example: “TutorialsPoint”, “Pinky”, etc. To create a string type variable, we use String keyword. Whereas Double is used to represent 64-bit floating point numbers. For example, 34.55656, 9.8283, etc. To create a double type variable, we use Double keyword. To convert double type variable into string we uses String() function. This function convert any data type into string. Syntax Following is the syntax − ...
Read MoreSwift program to create a class and object
This tutorial will discuss how to write swift program to create a class and object. Swift language is also an object oriented language. So it fully support class and objects. Class A class is a blueprint for the objects. To add the functionality to the class we can define properties and methods. Here, the constants and variables present inside the class are known as the class property whereas a function present inside a class is known as a method. Just like other programming language, Swift classes also support inheritance, type casting, deinitializers, reference, etc. Syntax Following is the syntax to ...
Read MoreSwift program to convert double type variables to int
This tutorial will discuss how to write swift program to convert double type variable to int. Swift support various datatypes and double and integers are one of them. Double is used to represent 64-bit floating point numbers. For example, 34.55656, 9.8283, etc. To create a double type variable we use Double keyword. Whereas Integer represent numeric values like 2, 3, 45, 6, etc. And to create integer type variable we use Int keyword. To convert double type variable into int we uses Int() function. This function convert any data type into integer. Syntax Following is the syntax − Int(variableName) ...
Read MoreSwift Program to convert int type variable to string
This tutorial will discuss how to write swift program to convert int type variable to string. Swift support various datatypes and string and integers are one of them. String is an ordered collection of characters. For example: “TutorialsPoint”, “Pinky”, etc. To create a string-type variable we use String keyword. Whereas Integers represent numeric values like 2, 3, 45, 6, etc. And to create integer-type variables we use the Int keyword. To convert int type variable into string we uses String() function. This function convert any data type into string. Syntax Following is the syntax − String(variableName) Below is a ...
Read MoreSwift Program to Print Hollow Right Triangle Star Pattern
This tutorial will discuss how to write swift program to print hollow right triangle star pattern. Star pattern is a sequence of “*” which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These star patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking. To create a hollow right triangle star pattern we can use any of the following methods Using nested for loop Using stride Function Below is a demonstration of the same − Input Suppose our given input is − Num = ...

This tutorial will discuss how to write swift program to print X star pattern.Star pattern is a sequence of “*” which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These star patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking. To create a X star pattern we can use any of the following methods Using nested for loop Using stride Function Below is a demonstration of the same − Input Suppose our given input is − Num = 5 Output The desired ...
Read MoreHow can Blockchain help Emerging Economies?
You could use Blockchain as a base to build financial services that fill gaps in the online market. Blockchain connects a network of entities and lets them share information. So, traditional databases only store data for one party at a time. Blockchain is a type of technology called a "decentralized ledger." Bitcoin was one of the first and most well-known ways of blockchain technology. However, most experts agree that blockchain technology has a lot of potential for other uses. Blockchain: A Novel Technology for Emerging Economies In 2017, the price of Bitcoin and Ethereum went up and down. It helped ...
Read MoreHow Blockchain changed the way money works?
What do you think the effects of Bitcoin technology will be? Don Tapscott, the CEO of the Tapscott Group, says that blockchains, the technology behind cryptocurrencies, could change the world economy. Tapscott talks with McKinsey's Rik Kirkland about the possible benefits of blockchains for working together and keeping track of transactions. Blockchains are a type of open-source, distributed database that uses cutting-edge cryptography. Every day, our global financial system deals with trillions of dollars, which helps billions of people worldwide. But the system has some flaws that lead to higher costs because of fees and delays, more trouble for everyone ...
