Introduction Here, we’ll be learning to write a C# program to Read the content of a file content line by line. There are various methods to do so. We will be discussing them one by one. File handling is done in C#. In most cases, the file is used to store data. File handling or file management in layman’s terms the various processes such as making the file, reading from it, writing to it, appending it, and so on. The reading and writing of files are the two most common operations in file handling. 1. Using File.ReadLines() method ... Read More

Introduction Let us try to understand the C# program to get the relative path from two absolute paths. We will understand using the URI( Uniform resource identifier) class and the MakeRelativeUri method. We will first understand the difference between absolute and relative paths. The absolute path includes all information required to locate a file or directory on a system. An example of an absolute path is C:\Program Files\Google Chrome\filename.exe. The relative path tells us the file's path with respect to the current directory on which the user is working. Considering the similar example mentioned above if the main executable ... Read More

Merging two sets means combining all the elements of a set into another set without any duplicates. In Swift, we can either use formUnion() function or for-in loop to merge the elements of two sets. Lets discuss both the methods in detail along with examples. Method 1: Using formUnion() Function To merge two sets we can use formUnion() function. The formUnion() function is used to insert the elements of the given sequence into the set. Here the sequence can be anything a set, array, etc. This function merge two sets without any duplicates. Syntax set1.formUnion(set2) Where set1 and set2 ... Read More

Introduction Let us try to understand the C# program to get the name of the file from the absolute path. We will see the usage of the GetFileName method which comes under the File class to get the name of the file, and another method GetFileNameWithoutExtension which will return the file name of the specified path string without extension. To get the relative path from two absolute paths, we will make use of the Uri class in C#. The Uri class provides several methods for working with URIs, including MakeRelativeUri, which we will use in our code. A file is ... Read More

In Swift, a set is used to define a unordered collection of unique elements. To iterate over an set swift provide inbuilt forEach() function as well as for-in loop. Lets discuss both the methods in detail along with examples. Method 1: Using for-in Loop To iterate over an set we can use for-in loop. The for-in loop iterate through each element of the set and display them on the screen one by one. Syntax for x in newSet{ print(x) } Where newset is the name of the set, and x variable store the current element from ... Read More

Introduction Let us see how to use the instrumental environment class of C# to write a C# Program to Get and Print the Command Line Arguments Using Environment Class. Knowing all the things about C#, we will now understand one of the uses of the system.environment class in C# and then we will learn to code a program that will get and print the command line arguments. Basically, it will take strings as arguments and will have its return type as a string. Before diving into the program we must have an overview of what is environment class in detail ... Read More

In Swift, a set is used to define a collection of unique elements, means a set doesn’t contains duplicate elements. In a set, the elements are not arranged in a particular order. Initialising a set means to store some information in the set. It can be done at the time of declaration or after declaration. We can initialise a set in various way like initialising a set without explicitly passing data types, initialising a set with explicitly passing data types, and using inbuilt insert() function. Now lets discuss all the method in detail along with examples. Method 1 In this ... Read More

Introduction On the computer, we can store files in a directory, also known as a folder. A directory also contains shortcuts to other directories and files. If we want to know what all files have stored in a directory then C# also offers an easy way to do so. In this article, we will be learning a C# program to get all files present in a directory. There are more than a couple of ways to know the files available in the directory. Let us discuss them in the upcoming sections. 1. GetFiles() Method For knowing the name ... Read More

In Swift, the Linear search algorithm is the easiest search algorithm. In a linear search algorithm, searching starts from index 0 and checks all the elements of the given array/sequence one by one until the desired element is found. If the desired element is found, then return the index of that element. If the desired element is not found, then return null. For example − We have an element M = 13, now we search M in the following array using a linear search algorithm − The linear search algorithm starts from index 0 and compares M=13 with ... Read More

In swift, Bubble sort algorithm is the easiest search algorithm. This algorithm sorts the elements by repeatedly swapping adjacent elements if they are not present at the right place. This algorithm works well only for small set of elements, it is not suitable for larger number of elements because its average and worst case time complexity is high. So the working of the bubble sort is − Suppose we have the following array − Now we sort the array in ascending order using the bubble sort. Here starting from the first index we compare the first and second element. ... Read More
