Variables and Data Types in Go

 Variables and Data Types in Go

In Go, you declare a variable using the var keyword followed by the variable name, the variable type, and optionally, an initial value.

var a int // declare an integer variable

a = 42    // assign a value to the variable

var b float64 = 3.14 // declare and initialize a float64 variable

Go supports several built-in data types, including integers, floats, booleans, and strings.
