Swift Program to Remove an Element from the Set
This tutorial will discuss how to write swift program to remove an element from the set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To remove an element from the set Swift provide an in-built library function named remove(). The remove() function delete the given element from the specified set. If the given element is not the part of the specified set, then it will return ...

This tutorial will discuss how to write swift program to add a new element in the set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To add a new element in the set Swift provide the following functions − insert() update() Below is a demonstration of the same − Input Suppose our given input is − MySet = [23, 45, 1, 46, 2] Insert ...
Read MoreSwift Program to Convert a String to Uppercase
This tutorial will discuss how to write swift program to convert a string to uppercase. A string is a sequence of characters for example, “RedCar”. Or we can say, string are used to represent textual data. Swift support a String data type which is used to create a String type variable, or we can say to represent strings. To convert the given string into uppercase Swift provide a in-built function named uppercased(). The uppercased() function is used to convert all the characters(either in lowercase or in uppercase or in both) of the given string into uppercase. This function does not ...
Read MoreSwift program to Get the Size of Set
This tutorial will discuss how to write swift program to get the size of set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To get the size of a Set Swift provide an in-built property named count. It will return the total number of elements present in the specified count. Below is a demonstration of the same − Input Suppose our given input is − MySet ...
Read MoreC++ Program to pass a string to the function
Any programming language that uses functions has code that is simpler, more modular, and simpler to change while being debugged. Functions are a remarkably beneficial component in a modular piece of code. A function can take arguments and perform certain operations on them. Like other primitive datatypes, we can also pass object types or arrays as an argument. In this article, we will see how to pass string-type data as a function argument in C++. Passing C++ like string argument to a function C++ supports stronger string objects which is actually a class with different member functions associated with them. ...
Read MoreC++ Program to Convert Vector to a List
Vectors in C++ are dynamic arrays that can contain any type of data, it can be user-defined or primitive. Dynamic is in the sense that the size of a vector can increase or decrease according to the operations. Vectors have support for various functions, for which data manipulation is very easy. Lists on the other hand are containers same as vectors, but list implementation is based on doubly linked lists compared to the array implementation of vectors. Lists offer the same constant time operations anywhere in it, that is the main feature of using lists. We take a look at ...
Read MoreC++ Program to Convert Array to Set (Hashset)
The array is a data structure that is available in C++ and is used to hold a sequential collection of elements of the same type. An array has a size that is fixed, but can be expanded or shrank if needed. It is important to think of an array as a collection of variables of the same type even though it is used to store a collection of data. Sets, or in this case unordered sets are a container that stores elements of a particular datatype in any order. A hash table is used to implement an unordered_set where keys ...
Read MoreC++ Program to convert primitive types to objects
Primitive datatypes in C++ are datatypes that are predefined in the language itself; like int, float, double, etc. Objects are instances of a class, and C++ being an object-oriented language, conversion between primitive data types and objects is necessary. A class serves as a data type's architectural plan. Although this doesn't describe any data specifically, it does specify what the class name signifies, i.e., what an object of the class will look like and what operations may be carried out on it. Conversion between a primitive data type to an object is not defined explicitly in the C++ language compilers, ...
Read MoreC++ Program to convert double type Variables into int
In C++, variables of the int type can only hold positive or negative integer values; they cannot hold fractional values. There are float and double values available for this purpose. In order to store fractional numbers with up to seven digits after the decimal point, double datatype was created. Integer to double datatype conversion can either be done automatically by the compiler (known as "implicit" conversion) or explicitly requested by the programmer to the compiler (known as "explicit" conversion). In the sections that follow, we go over the various conversion methods. Implicit Conversion The compiler does implicit type conversions automatically. ...
Read MoreC++ Program to convert int Variables into double
Int type variables in C++ are used to contain positive or negarive integer values, but this type is unable to contain fractional values. For that, there are float and double values. Double datatype is specifically designed to hold fractional values upto seven digits after the decimal point. Conversion between integer and double variables can be automatically handled by the compiler, known as ‘implicit’ conversion or can be explicitly triggered by the programmer to the compiler. We discuss the different ways of conversion in the following sections. Implicit Conversion Implicit type conversions are done automatically by the compiler. For this to ...
