GO (golang) Tutorial for Beginners - #Day-28 : GO pointers and Functions

Title: GO pointers and Functions in Go Language | Go Programming Tutorial

Description:

In Go, a pointer is a variable that holds the memory address of another variable. Pointers are useful for efficiently passing large data structures or modifying variables inside functions. A pointer is declared using the * symbol, and the & symbol is used to get the address of a variable.

Functions in Go are first-class citizens, meaning they can be assigned to variables, passed as arguments, and returned from other functions. Functions can accept parameters, return multiple values, and be defined with named return values. By combining pointers and functions, Go allows for powerful and flexible programming patterns, such as passing large structures by reference or modifying variables within a function.

In Go, pointers can be used in functions to allow the function to modify the original variable passed to it, rather than a copy. Here's a step-by-step explanation on how to use pointers in Go functions:

Declare a Pointer: Use the * symbol to declare a pointer type.

Get the Address of a Variable: Use the & symbol to get the memory address of a variable.

Dereference a Pointer: Use the * symbol to access the value stored at the pointer's address.

Function with a Pointer Parameter: Define a function that takes a pointer as a parameter to modify the original variable.
