Golang program to create a temporary file
In Go programming language we can use ioutil.TempFile function to create a temporary file. To create a new temporary file in the default temporary directory, this program uses the ioutil. TempFile function. The directory in which the file should be created is the first argument to TempFile, and the pattern to use for the file name is the second argument. The pattern in this instance is "temp-*.txt, " leading to a file name like "temp-123456789.txt". Syntax Ioutil.TempFile In Go programming language, this function is a part of ioutil package and is used to create a temporary file. A ...
Read MoreGolang program to create a new file
Golang has two internal function – os.create and ioutil.WriteFile to create a new file. The "file" is a disk-based file that a Go program may read from or write to. In Go, the OS can be used to represent a file. os package file type that offers ways to open, read from, write to, and manipulate files. Method 1: Using os.Create Command In this method, the os.Create function uses the specified name to create a new file or truncate an existing one. When the function has completed running, the file is closed using the defer command. Syntax Os.Create ...
Read MoreGolang program to convert file to byte array
In Go programming language we can use byte function and ioutil.ReadFile function to convert a file into byte array. The os package file type that offers ways to open, read from, write to, and manipulate files whereas array is a fixed-size group of identical elements that may be accessed by their respective indexes, which are integers with a zero-based basis. An array's size is predetermined at the moment of declaration and cannot be altered later on. When storing a set of data with a known number of elements, arrays in Go are handy, but they have some drawbacks, such as ...
Read MoreGolang program to add elements to a linkedlist
In Golang, we can use node struct and linkedlist struct to add elements to a linkedlist. A linkedlist is a data structure made up of a series of nodes, each of which includes an element and a reference to the node after it in the sequence. It is a linear data structure with pointers connecting the items, and from the first node (head) to the last node, each node can be visited (tail). As opposed to arrays, which require all elements to be shifted, linked lists just require altering the pointers of the adjacent nodes, making them helpful in situations ...
Read MoreGolang program to access elements from a linked list
In Go Programming language, a linked list is a data structure which contains a node that further contains two values, the data and the next, where next points to the next node in the list. We will use two methods in this program to access elements from a linked list. In the first example iteration will be used and in the second example a variable current will be used to access the elements. Method 1: Using Iteration This program builds a linked list with three members and iterates through it to access and output each element's value. The output ...
Read MoreGolang program to remove elements from the linked list
In Go, a linked list is a linear data structure with pointers connecting the items, and from the first node (head) to the last node, each node can be visited (tail). We will execute the program of removing elements from the linked list using two examples. The first example uses node struct whereas the second example uses a dummy node Method 1: Using Node Struct This code creates a Node struct that has two fields: Value and Next, which links to the next node in the list. The remove_node method removes the node with the supplied value from the list ...
Read MoreGolang program to add elements at first and last position of linked list
In golang, a linked list is a unique data structure in which there is a value in the node and the next pointer which points to the next node. The list's initial node is referred to as the head, while the list's last node which points to nil depicts the end of list. We will add elements at the first and last position of the linked list using two examples. In the first example node struct will be used and in the second example ListNode struct will be used. Method 1: Using Node Struct In this method, we will use ...
Read MoreDifference Between B-tree and Binary tree
There are two types of non-linear data structures namely, B-Tree and Binary Tree. These two terms sound similar but they are absolutely different from each other. The most basic difference between a B-Tree and a Binary Tree is that a B-Tree is used for data storage on a disk, whereas a Binary Tree is used for data storage in RAM. Read this article to learn more about B-tree and Binary Tree and how they are different from each other. What is a B-Tree? B-Tree, also called Balanced Sort Tree, is a type of balanced M-way tree. In a B-tree, the ...
Read MoreGolang program to implement the Queue data structure
In this Golang program, a queue is a data structure that works on the First-In-First-Out (FIFO) principle where elements are added to the rear and removed from the front. Although Go doesn't come with a built-in queue data structure, slices, linked lists, and other data structures can be used to build one. We will use two methods to implement queue data structure using slices and linked list. Method 1: Using Slice Method The fundamental operations for a queue data structure: Enqueue, Dequeue, and IsEmpty are implemented in this implementation, which employs a slice to hold the items in the ...
Read MoreGolang program to create a string object
In Golang, a string cannot be modified after they have been created. A built-in type in Go, the string type can be used in a variety of ways much like any other data type. In this article, we will use three methods to create a string object. The first method involves using of double quotes and backticks, in the second method strings.Replace() function is used and in the third method, a byte function is used to execute the program. Method 1: Using double quotes and backticks Two string objects, str1 and str2, are created in this program. Backticks (') are ...
