Golang Program to Check Whether Two Matrices are Equal or Not
In this tutorial, we will write a golang program to check whether two matrices are equal or not. A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array. Check Whether Two Matrices are Equal or Not using If Statment In this example we will compare the equality of two matrices using if condition statements. Algorithm Step 1 − Import the fmt package. Step 2 − Start the main() function. Step 3 − Initialize and assign values the two matrices. Step 4 − Print these matrices on the screen. Step 5 − Now use the equality(==) ...
Read MoreGolang Program to Calculate Standard Deviation
In this tutorial, we will write a go language code to calculate the standard deviation. The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. It is calculated as the square root of the mean. Find the Standard Deviation Using External Functions In this example, we will write a go language program to calculate the standard deviation using user-defined functions. Algorithm to the Above Program Step 1 − Import the fmt, math, and start. Step 2 − Create the standardDeviation() function. This function uses a for loop to intend ...
Read MoreGolang Program To Add Two Matrices
In this tutorial, we will write a go language program to add two matrices. A matrix is a collection of numbers that are arranged in rows and columns, which is a two-dimensional array. Go Language Program To Add Two Matrices Let us now look at a go language program to add two matrices using loops. Algorithm to the Above Program Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating two matrices named matrixA and matrixB and store values in them. Step 4 − Print ...
Read MoreGolang Program For Array Rotation
Introduction In this tutorial, we will see to write a go language program to rotate an array. We will write two programs for this. One to rotate the array to left and another to rotate it to right. Golang Program to Rotate an Array to Left The following code illustrates how we can rotate an array to left using a user defined function. Algorithm to the above Program Step 1 − Import the fmt package that allows us to print anything on the screen. Step 2 − Create a function named rotateLeft() which returns the final array after rotating it. ...
Read MoreGolang program to print a 2D array?
Two−dimensional arrays are commonly used in Go. For example, storing data in a table requires a 2D array. In this tutorial, we will be discussing the approach to printing a 2D array in Golang programming. But before writing this code, let’s briefly discuss the two−dimensional array. What is a 2D Array? A 2D array is comprised of rows and columns. Its nature is similar to a normal array with a fixed length. It is homogeneous in nature, i.e., all the elements stored in a 2D array should be of the same data type. If a 2D array has ‘r’ rows ...
Read MoreGolang Program to Create a Simple Class?
In this tutorial, we will be discussing the approach to creating a simple class in Golang programming. However, before writing the code for this, let’s briefly discuss the concept of class. What is Class? A class is a template or blueprint for creating objects. A class binds together all the elements of a program and it is an essential part of object−oriented programming. Nevertheless, Go language does not support the ‘class’ keyword unlike other languages like Java, C++, etc. which are object−oriented languages. However, this does not limit Go to using the functionality of a class. Go keeps up with ...
Read MoreGolang Program to get the denominator from a rational number
In this article, we will discuss how to get the denominator from a rational number. Rational numbers − In mathematics, rational numbers are defined as numbers that can be expressed in the form of a/b where a and b are integer values. For example- 1/3, 5/8 etc. Note that the denominator of a rational number can never be zero. Syntax func NewRat(a, b int64) *Rat func (x *Rat) Denom() *Int NewRat() function takes two integer numbers as input arguments and returns a rational number in the form of a/b. here a is the numerator and b is the denominator ...
Read MoreGolang Program to Convert Character to String
In this article, we are going to learn about how to convert characters to string go programming language. Chars − Go language does not have a char data type on the contrary characters in go language are represented by rune data type. Rune represents a character value that is encoded in UTF-8 format. The size of the runes is 32-bits. Strings − String data type is used to store a sequence of characters. it can be in the form of literals or alphabets. The size of the string variable is 1 byte or 8 bits. There are two approaches to ...
Read MoreGolang Program to Create an Interface
In this article, we are going to learn about how to create an interface using golang programming INTERFACE − In the go language, an interface is a custom type that is used to specify one or more method signatures. An interface is abstract i.e. we cannot create an instance of the interface but we can create a variable to the interface type and assign this variable to the struct or class that has methods needed by the interface. Syntax type interface_name interface { // method signatures } Example 1 To define an interface first we need ...
Read MoreGolang Program to Create a Class and Object
In this article we are going to learn how to create class and object. Structs − Go language does not have classes. To create an object in the go programming language we can specify structs and store key-value pairs in it. A struct is a user-defined data type that is used to store data together. The values so stored may have the same or different data type. Syntax The syntax to define a structure is as follows − type name_of_struct struct { name_1 type_1 name_2 type_2 name_3 type_3 ...
