The Mod() function in Go is “used to find the modulus or remainder from the floating-point division of the two arguments (x/y)”. To use the Mod() function, you need to import the math package to your file and access the Mod() function within it using the (.) notation. Syntax func Mod(x, y float64) float64 Parameters The Mod() … Read more
To create an empty slice in Golang, you can use the “empty pair of square brackets” or “make()” function. Method 1: Using a literal syntax with empty brackets Use a literal syntax with empty brackets to create an empty slice in Go. You need to use the := operator and an empty pair of square brackets … Read more
Type Assertions A type assertion in Golang is “used to provide access to an interface value’s underlying concrete value”. A type assertion does not convert an interface to another data type. Instead, it provides access to the underlying concrete value of the interface. This is normally what you want, as it allows you to work … Read more
To check if a slice contains an element in Golang, you can use either the “slice.Contains()” function or “for loop”. Method 1: Using the slice.Contains() function Starting with version 1.18, Go introduces a new function called a slice.Contains() that checks if a slice contains a specific element. Syntax func Contains[E comparable](s []E, v E) bool Parameters … Read more
There are three methods to initialize an array in Go. Method 1: Initializing an Array with “array literal” The easiest way to initialize an Array in Golang is to use the “array literal”. An array literal is a sequence of values enclosed in curly braces {} and separated by commas. When initializing an array, you need … Read more
To pass the default parameter to a function in Golang, you can use a “variadic function”, “struct with a default value”, or “map with a default value”. Method 1: Using a variadic function A variadic is a function that accepts a variable number of arguments. In Go, you can define a variadic function using the … syntax … Read more
To convert a boolean to a string in Go, you can use the “strconv.FormatBool()” or “fmt.Sprint()” function. Method 1: Using strconv.FormatBool() function You can use the “strconv.FormatBool()” function to convert a boolean to a string. The strconv.FormatBool() is a built-in function that takes a Boolean value as an argument and returns a string representation of that … Read more
To find an absolute value in Golang, you can use the “math.Abs()” function. The math.Abs() is a built-in function “used to find the absolute value of any given number”. Syntax math.Abs(input) Parameters An input is a floating point value of type float64. Return value The Abs() function returns a floating point value of type float64. If … Read more
To generate a random boolean value in Golang, you can use the “Intn()” function from the math/rand package. The “rand.Intn()” function in Go is used to generate a random integer in the range [0,n). It panics if n <= 0. Example 1: Use the rand.Intn() function package main import ( “fmt” “math/rand” “time” ) func … Read more
To get the current working directory in Golang, you can use the “os.Getwd()” function or the “filepath.Abs(‘.’)” function. The current working directory is the directory in which a process starts, and it is usually the directory in which the current program or executable file is located. Method 1: Using the os.Getwd() function The os.Getwd() function … Read more
