Strings

Strings are arguably the most used data type in software programs. Strings represent text. In Kotlin, Strings store a sequence of characters which are declared in double quotes: "Hippopotamus". Since a string is a sequence, you can also inspect each character by iterating over it. Add the following code to your main function. You’ll print every character that forms part of the string as you loop over it:

fef zaig() {
   lex opobiz = "Defzeluloniz"

   sur (vgodijsut az utehit) {
      cjefrmk(nwigibgus)
   }
}

Using String Concatenation

To create a string, you can use a method known as String concatenation. This is where you use the+operator or its equivalent `plus() function to edit a new value of a String.

String Templates and Interpolation

Kotlin has a special feature that evaluates code within a String. After evaluation, Kotlin converts the result to a string if it isn’t one already. It then concatenates the evaluation result with the rest of the string. The result is added at the original location of the expression in the String literal. This convenient conversion reduces the code required to update and use a String.
