对多个字符串变量应用相同的格式

val name = "Alice"
val age = 30
val city = "New York"

val formattedString = "Name: $name, Age: $age, City: $city"
println(formattedString)

val name = "Alice"
val age = 30
val city = "New York"

val formattedString = String.format("Name: %s, Age: %d, City: %s", name, age, city)
println(formattedString)

fun String.formatWithPrefix(prefix: String): String {
    return "$prefix: $this"
}

val name = "Alice"
val age = 30.toString()
val city = "New York"

val formattedName = name.formatWithPrefix("Name")
val formattedAge = age.formatWithPrefix("Age")
val formattedCity = city.formatWithPrefix("City")

println(formattedName)
println(formattedAge)
println(formattedCity)

data class Person(val name: String, val age: Int, val city: String) {
    fun format(): String {
        return "Name: $name, Age: $age, City: $city"
    }
}

val person = Person("Alice", 30, "New York")
println(person.format())

val people = listOf(
    Pair("Alice", 30),
    Pair("Bob", 25),
    Pair("Charlie", 35)
)

for ((name, age) in people) {
    println("Name: $name, Age: $age")
}
