Arrays and Slices give Arrays Arrays in Go are fixed-size sequences of elements of the same type. Once declared, their size cannot change. Example 1: Declaring and Initializing an Array gopackage mainimport “fmt”func main() { // Declare and initialize an array of integers var numbers [5]int numbers = [5]int{1, 2,…

Defining Functions in Go In Go, functions are defined using the func keyword, followed by the function name, parameters (if any), return type (if any), and the function body enclosed in curly braces {}. Here’s an example: gopackage mainimport “fmt”// Function definition with parameters and return typefunc add(a, b int)…

Conditional Statements (if, else, switch) In Go, conditional statements (if, else, switch) are essential for controlling the flow of execution based on certain conditions.
