Variable Declaration and Type Inference

Go allows two ways to declare variables. The `var` keyword with explicit type, or the `:=` short syntax which infers the type from the value. Variables declared with `:=` inside a function are called short variable declarations.

snippet.go
go
package main
 
import "fmt"
 
func main() {
    // Explicit type declaration
    var name string = "Go"
    age := 25 // Type inferred as int
    
    fmt.Printf("Language: %s, Age: %d\n", name, age)
}

Breakdown

var name string = "Go"

Explicit declaration with var keyword and type string

age := 25

Short declaration where type is inferred as int automatically

fmt.Printf(...)

Formatted print using printf with %s for string, %d for int
