A matrix is a rectangular array of numbers. Or we can say that a matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. In this article, we will learn how to write a swift program to calculate the sum of matrix elements. So here, using the following methods we calculate the sum of matrix elements. Sum of square matrix elements Sum of any matrix elements For example, we have the following matrix − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 4 & 5 & 6ewline4 & 7 ... Read More

A matrix is an arrangement of numbers in rows and columns. The matrix can be of various types like square, horizontal, vertical, etc. In this article, we will learn how to write a swift program to calculate the sum of columns of matrix elements. Here we are using the following methods to find the sum of the column’s elements − Using a nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use a nested for-in loop to find the sum of columns of matrix elements. Algorithm Step 1 − Create a function. Step ... Read More

What is a string and a substring? 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 ... Read More

What is String Concatenation? In Go, string concatenation is the process of combining two or more strings into a single string. There are several ways to concatenate strings in Go. We shall discuss them in this article. Method 1: By Using User-Defined Function The function that we create will take two strings as arguments and will return the resultant string by combining both of them as the result. Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then create a function that will join the two strings together. The function accepts two ... Read More

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\ ...

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 More

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

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 ...

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
