Go language Program to calculate the sum of matrix elements
What is a Matrix? A matrix is a collection of numbers that are arranged in rows and columns, which is a two-dimensional array. Here we will use three examples to find the sum of elements and compare each element of the matrix for the same using the Golang program. Algorithm Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating a matrix naming matrixA. Step 4 − Print the matrix on the screen using fmt.Println() function. Step 5 − Initialize a new variable called ...
Read MoreGolang Program to Show Usage of Static keyword in Class
What is Static Keyword in Golang? The term "static" is used to describe variables, functions, and methods that have a fixed or unchanging value or behavior. In Go, the static keyword does not exist. In go we use the term "variables" to describe the memory locations where data is stored and manipulated. Static variables have a property of preserving their value even after they are out of their scope! Hence, static variables preserve their previous value in their previous scope and are not initialized again in the new scope. Algorithm Step 1 − First, we need to import ...
Read MoreGolang Program to Print Boundary Elements of a Matrix
What is Boundary Elements? In go programming language. the boundary elements of a matrix are the elements that are located on the outer edge of the matrix. They are located at four positions i.e the first row, the last row, the first column and at the last column. In a matrix of size m x n, the top boundary elements are the elements in the range matrix[0][0] to matrix[0][n-1], the bottom boundary elements are the elements in the range matrix[m-1][0] to matrix[m-1][n-1], the left boundary elements are the elements in the range matrix[0][0] to matrix[m-1][0], and the right boundary elements ...
Read MoreGolang Program to Sort the 2D Array Across Columns
What is 2D array in Golang? In Go programming language, a 2D array is an array of arrays, where each element of the outer array is a simple array itself. The code to declare a 2d array of size 2 X 3 can be done by writing var array [2][3]. It's important to note that 2D arrays have a fixed size, and once they are created, their size cannot be changed. If you need a dynamic 2D array, you can use a slice of slices. Here is an example of sorting a 2d array across columns − Input 3 2 1 6 4 5 ...
Read MoreGolang Program to Convert String to an Array
In Go Language, we have various data types to store data and the String data type is the one that is used to store a sequence of characters. The size of string variable is 1 or 8 bits. An array on the other hand is a data type that is used to store data at contiguous memory locations. Syntax func fields(s string) []string fields() function is present in strings package and is used to convert a string to an array of string. This function takes a string value as an argument and returns the corresponding array as the result. ...
Read MoreGolang Program to Show Usage of Access Modifier
In go programming language, there are two types of access modifiers i.e Exported and un-exported. Identifiers that are exported from the package in which they are specified are known as exported identifiers. They always begin with a capital letter. These are only valid in the package in which they are defined. Identifiers that are not exported from any package are referred to as un-exported identifiers that are written in lowercase. 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 ...
Read MoreGolang Program to Convert String to Object
In Golang program, a string is a data type that contains literals and characters whereas an object is a data type created from classes by keeping similar types of properties together. In this article, we will look at two methods by which we can convert a string to an object in go programming language. Syntax func Split(str, sep string) []string Split() function is used to split a string through a provided separator. This function is present in strings package and it accepts the string to split as an argument along with a separator. The function then returns the final ...
Read MoreGolang Program to demonstrate the escape sequence characters
In the go programming language, there are several types of special escape sequence characters. Usage of each one of them implements a different type of functionality. We shall discuss each one of them one by one in the upcoming examples. Example 1 In this example, we will write a go language program to demonstrate the backlash (//) character. It is used to display a slash in the output of the program. package main import "fmt" func main() { fmt.Println("Program to display a backslash using in the program") } Output Program to display a backslash using in the program\ ...
Read MoreGolang Program to demonstrate the example to write double quotes in a string
In Golang there are various techniques of printing double-quotes in the string. In this article, we are going to learn those techniques with various example. Syntax func Quote(s string) string Quote() function is present in strconv() package and is used to add a given string literal in double quotes. The function accepts the string variable that is to be quoted as an argument and returns the string after adding double quotes to it. func Sprintf(format string, a ...interface{}) string This function returns a formatted string. It takes a number of arguments in string format. The first argument should ...
Read MoreGolang Program to get characters from a string using the index
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 ...
