variables in golang

In Go, variables are used to store and manipulate data. They have a specific type, which determines the kind of data they can hold. Here are the steps to declare and initialize variables in Go:

1. Declare the variable: You start by declaring the variable using the var keyword, followed by the variable name. For example, var age int.

2. Specify the variable type: After declaring the variable, you specify its type using the type name. In this example, the type is int, which represents integers.

3. Initialize the variable: You can initialize the variable with an initial value using the assignment operator =. For example, age = 25.

Alternatively, you can declare and initialize a variable in a single step using the shorthand syntax. For example, name := "John" declares a variable named name and initializes it with the value "John". The type of the variable is inferred from the assigned value.

1. Use the variable: Once the variable is declared and initialized, you can use it in your code. For example, fmt.Println("Age:", age) prints the value of the age variable.

Note that Go is a statically typed language, which means that once a variable is declared with a certain type, its type cannot be changed later.

That covers the basics of declaring and initializing variables in Go. Let me know if you have any further questions.
