Strings are defined using the built-in `string` type like this:

const a: string = "Hello Alice";

```

## Concatenating strings
|
||
|
|
|
||
|
|
Strings can be concatenated using the `^` operator.
|
||
|
|
|
||
|
|
<!--DOCUSAURUS_CODE_TABS-->
|
||
|
|
<!--Pascaligo-->
|
||
|
|
```pascaligo
|
||
|
|
const name: string = "Alice";
|
||
|
|
const greeting: string = "Hello";
|
||
|
|
// Hello Alice
|
||
|
|
const full_greeting: string = greeting ^ " " ^ name;
|
||
|
|
// Hello Alice! (alternatively)
|
||
|
|
const full_greeting_exclamation: string = string_concat(full_greeting, "!");
|
||
|
|
```
|
||
|
|
<!--Cameligo-->
|
||
|
|
```cameligo
|
||
|
|
let name: string = "Alice"
|
||
|
|
let greeting: string = "Hello"
|
||
|
|
let full_greeting: string = greeting ^ " " ^ name
|
||
|
|
```

## Slicing strings
|
||
|
|
|
||
|
|
Strings can be sliced using the syntax specific built-in built-in function:
|
||
|
|
|
||
|
|
<!--DOCUSAURUS_CODE_TABS-->
|
||
|
|
<!--Pascaligo-->
|
||
|
|
```pascaligo
|
||
|
|
const name: string = "Alice";
|
||
|
|
// slice = "A"
|
||
|
|
const slice: string = string_slice(0n, 1n, name);
|
||
|
|
```
|
||
|
|
<!--Cameligo-->
|
||
|
|
```cameligo
|
||
|
|
let name: string = "Alice"
|
||
|
|
let slice: string = String.slice 0n 1n name
|
||
|
|
```
|
||
|
|

|
> ⚠️ Notice that the `offset` and slice `length` are `nats`

## Aquiring the length of a string
|
||
|
|
|
||
|
|
The length of a string can be found using the syntax specific built-in function:
|
||
|
|
|
||
|
|
<!--DOCUSAURUS_CODE_TABS-->
|
||
|
|
<!--Pascaligo-->
|
||
|
|
```pascaligo
|
||
|
|
const name: string = "Alice";
|
||
|
|
// length = 5
|
||
|
|
const length: nat = size(name);
|
||
|
|
```
|
||
|
|
<!--Cameligo-->
|
||
|
|
```cameligo
|
||
|
|
let name: string = "Alice"
|
||
|
|
let length: nat = String.size name
|
||
|
|
```
