Swift Program to Calculate the Sum of Natural Numbers
This tutorial will discuss how to write a swift program to calculate the Sum of Natural Numbers. Natural numbers are the set of whole numbers excluding 0. In other words, natural numbers are the numbers which includes all the positive numbers starting from 1 to infinity. It does not contain negative numbers and 0 in it. For example 2, 3, 67, 49, etc. They are also known as counting numbers. We can find the sum of natural numbers by adding given natural numbers using arithmetic addition operator (+). For example, we have 8 so the sum of natural numbers is ...
Read MoreSwift Program to Find the Surface area and Volume of Cuboid
This tutorial will discuss how to write a swift program to find the surface area and volume of cuboid. A Cuboid is a 3-dimensional solid figure which contains six rectangular faces, eight vertices and twelve edges. It has three dimensions known as length, breadth, and height and if a cuboid has integer edges then the cuboid is the perfect cuboid. The opposite edges of the cuboid are always parallel to each other and the angle formed by all vertices are 90 degrees Surface area of cuboid Surface area of a cuboid is the total space occupied by the cuboid. ...
Read MoreSwift Program to Check whether the input number is a Neon Number
This tutorial will discuss how to write a swift program to check whether the input number is a Neon Number. In a number system, a number whose sum of digits of square of the number is equal to the number is known as neon number. Below is an example of the neon numbers − Let’s see if number 9 is a neon number or not? - The square of 9 is 81 and the sum of 81 is 9 So 9 is a neon number Let’s take another example - 15 The entered number is not a neon number Here, ...
Read MoreSwift Program to Calculate Compound Interest
This tutorial will discuss how to write a swift program to calculate compound interest. The interest applied to the principal and interest together over a certain period of time is known as compound interest. In other words, the compound interest is known as the interest on interest. It is calculated after calculating the amount. Formula Following is the formula of compound interest − Amount(A) = Principal(P)(1 + Rate/100)Time(t) C.I = Amount(A) - Principal(P) Where Principal(P) − Principal amount represents the amount that is initially invested. Rate(R) − Rate represents the interest rate, that applied to the principal amount for the ...
Read MoreSwift Program to Generate Multiplication Table
This tutorial will discuss how to write a Swift program to generate Multiplication Table. A multiplication table is a list or table of multiples of a specified number. We can create a multiplication table by multiplying a number with whole numbers. Generally, a multiplication table is created upto 10 times but you can create it according to your need. Below is a demonstration of the same − Suppose our given input is − The desired output is − Following is the multiplication table is 9 9 * 1 = 10 9 * 2 = 20 9 * 3 ...
Read MoreSwift Program to Calculate the Power of a Number
This tutorial will discuss how to write a swift program to calculate the power of a number. Power of a number means how many times a number is used in multiplication, for example, 16 ^2 = 16 * 16 = 256 or 16 to the power of 2. It is also known as exponent or indices. Below is a demonstration of the same − Suppose our given input is − Number - 16 Exponent Value is - 3 The desired output is − Final result is 16^3 = 4096 Calculating power of a number using recursion We can calculate the ...
Read MoreDifference Between HashMap and TreeMap in Java
Both HashMap and TreeMap are considered to be Map classes because they both carry out the responsibilities of the Map interface. A Map is an object that stores key-value pairs, in which there is only one instance of each key but there may be multiple instances of the value. The hash table is a type of data structure that is utilised by the HashMap class. As a form of data storage, the red-black tree is utilised by the TreeMap.What is a HashMap?A HashMap uses a data structure known as the hash table in order to store the map's key-value pair. ...
Read MoreHow to Swap Two Numbers in Swift Program?
This tutorial will discuss how to write a swift program to swap two numbers. Swapping of two variables means mutually exchanging the values of two variables.Swapping using temporary variableGiven two variables Number1 and Number2 now we swap their values with each other using a temporary variable Numtemp. It is the most easiest way to swap two numbers.AlgorithmThe algorithm is explained below −Step 1 − Declare three integer variables: Number1, Number2 and Numtemp(temporary variable.)Step 2 − Assign values to Number1 and Number2Step 3 − Assign Number1 to NumbertempStep 4 − Assign Number2 to Number1Step 5 − Assign Numbertemp to Number2Step 6 ...
Read MoreSwift Program to Find the Area of a Circle
This tutorial will discuss how to write a swift program to find the area of a Circle.In a circle, an area is known as the space that is enclosed inside the boundaries of the circle in the two-dimensional plane. Suppose we have a round tea table now the area of the circle helps us to find how much cloth we required to cover the top of the table. We can calculate the area of the circle with the help of the radius or diameter, here, We are going to use the formula of area of the circle −Area of the ...
Read MoreHow to Add two Numbers in Swift Program?
This tutorial will discuss how to write a swift program to add two numbers.Adding two numbers in Swift language is simple and can be performed with the help of the addition arithmetic operator(+). The arithmetic addition operator (+) uses two numbers as operands and returns their sum as output.In this operator, both the operands should be of the same data types, For example swift allows adding a float into float without an issue but if we will try to add different types of data types using (+) operator then the compiler will raise an error, For example adding an Int ...
