What is string in golang? In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ("") and can contain any combination of letters, numbers, and symbols. They are commonly used to store text and are often used as input and output in programs. Method 1: By Using An External Function In this method, the function that we create will accept the string whose length is to be calculated as an argument and returns the final length of the ...

In Golang, there are various methods to get characters from a string with the help of an index. In this article, we are using external functions as well as by using internal functions defined in the go language. Method 1: Using User-Defined Function In this method, the function that we create will take the string whose character is to be determined along with the integer type index of the string and will return the character of the string present at that index. Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then, create ... Read More
An Armstrong number, also known as a narcissistic number, is a number that is equal to the sum of its own digits each raised to the power of the number of digits. Here we will show different approaches about how we can print the Armstrong numbers in go programming language. Method 1: By Using Math Package In this example we will use different functions present in math package in order to print the Armstrong numbers between said limits. Syntax func Pow(a, b float64) float64 The pow() function is present in math package and is used to raise one number ... Read More
In go language, a long is not a separate data type but it is an extension made from the integer data type to store even larger values of integers. The main difference between an int data type and long data type is that an int data type is 32 bits whereas long data type is 64 bits. Here we will learn about different techniques to convert long types variables to int using go programming language. Method 1: By Using Type Casting In this example we will use the type casting approach to convert the long data type variables to int. ... Read More
We can add a shadow to a canvas circle using Fabric.js by creating a new circle object, then setting the "shadow" property of the object to an object containing the desired shadow properties such as color and offset. Fabric.js is an open-source JavaScript library that allows developers to create and manipulate HTML5 canvas elements with ease. It simplifies the process of creating, editing and animating canvas elements by providing a set of powerful and flexible APIs. With Fabric.js, developers can create complex canvas graphics, animations, and interactive elements without having to deal with the low-level canvas API. It also provides ... Read More
A substring in Go is a portion of a larger string. It is specified by providing a start index and a length, and it contains the characters of the original string starting at the start index and going up to the specified length. The characters in a substring are still a part of the original string and share the same memory. In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ("") and can contain any combination of ... Read More
In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ("") and can contain any combination of letters, numbers, and symbols. They are commonly used to store text and are often used as input and output in programs. Syntax func len(v Type) int The len() function is used to get the length of a any parameter. It takes one parameter as the data type variable whose length we wish to find and returns the integer value ... Read More
A string in Golang is a collection of characters. Since strings in Go are immutable, they cannot be modified after they have been produced. Concatenating or adding to an existing string, however, enables the creation of new strings. A built-in type in Go, the string type can be used in a variety of ways much like any other data type. Algorithm Step 1 − Create a package main and declare fmt(format package) and sort package in the program where main produces executable codes and fmt helps in formatting input and output. Step 2 − Create a main function and ... Read More
An array is a fixed sequence of elements in which the elements are placed at contiguous memory locations. We will shuffle and randomly place the elements of the array. In the first case we will use fisher-yates shuffle algorithm. Let’s see how we can execute it using different logics in the Golang code. Syntax rand.Seed(value) Rand.Seed() function is used to generate random numbers. It takes a user input as argument which is the upper limit for generating random numbers. func Now() Time The Now() function is defined in time package. this function generates the current local time. to ...

In go programming language, string is one of the data-types that can be used for various application. It is a collection of characters and is also immutable. In go programming language a string can't be modified after they have been created. In this article, we are going to study different techniques to compare two given strings. Syntax bytes.Equal(s1, s2) Two slices of bytes ([]byte) are compared using the Equal() method to see if they are equal. If the two slices of bytes are equal, it produces a boolean result (true or false) reflecting that fact. strings.Compare(s1, s2) The ... Read More
