| Operator         | Result | Description                                                                                          |
| ---------------- | ------ | ---------------------------------------------------------------------------------------------------- |
| char **+** char  | str    | Returns a string of two characters.                                                                  |
| char **+** str   | str    | Returns a string as the result of adding a string to a character.                                    |
| str **+** char   | str    | Returns a string as the result of adding a character to the string.                                  |
| char **=** char  | char   | Assignment operator.                                                                                 |
| str **+=** char  | str    | Appends a character to the string                                                                    |
| char **==** char | bool   | Returns *true* if the two characters are equal and *false*, otherwise.                               |
| char **>** char  | bool   | Returns *true* if the first character is greater than the second and *false*, otherwise.             |
| char **<** char  | bool   | Returns *true* if the first character is less than the second and *false*, otherwise.                |
| char **!=** char | bool   | Returns *true* if the two characters are not equal and *false*, otherwise.                           |
| char **>=** char | bool   | Returns *true* if the first character is greater than or equal to the second and *false*, otherwise. |
| char **<=** char | bool   | Returns *true* if the first character is less than or equal to the second and *false*, otherwise.    |

## Functions

### int( char c ) int

The *int* function returns the numeric value of a character.

### str(char c) str

The *str* function converts a character to a string and returns this string.
