Variable Declaration & Initialization

fun main() {
        // Variable declaration and initialization
        var num int = 10
        var name string = "John Doe"
        var flag bool = true
        
        // Variable declaration without initialization (zero value assignment)
        var age int
        var score float64
        var isValid bool
        
        // Short variable declaration (with type inference)
        count := 5
        message := "Hello, world!"
        isFound := false
        
        // Printing the variables
        fmt.Println(num)
        fmt.Println(name)
}
