`.` (Dot) `.` (dot) is a special character in computing and programming languages that primarily serves two main purposes: 1. Current Directory: * In many file systems, such as Unix-like systems (e.g., Linux, macOS), ‘`.`’ represents the current working directory. * When used as a path, ‘`.`’ refers to the directory containing the current file or command being executed. Example 1: “` ls . “` This command lists the contents of the current directory. 2. Member Access Operator: * In object-oriented programming languages, ‘`.`’ is used as a member access operator. * It allows access to attributes (properties) or methods of an object. Example 2 (Python): “`python class Person: name = “John Doe” person = Person() print(person.name) # Output: John Doe “` Parent Directory: While ‘`.`’ represents the current directory, a special character called ‘..’ (double dot) is used to refer to the parent directory of the current directory. 1. Parent Directory Navigator: * In file systems, ‘..’ is used to navigate to the directory one level above the current directory. * It can be used in pathnames to move up the directory structure. Example 3: “` cd .. “` This command moves to the parent directory of the current directory. 2. Superclass Access Operator: * In object-oriented programming, ‘..’ is sometimes used as a special operator to access attributes or methods of the superclass of the current class. Example 4 (Java): “`java class Child extends Parent { @Override public void print() { // Access superclass method using ‘..’ super.print(); } } “` Note: * The usage of ‘..’ as a superclass access operator varies depending on the specific programming language. * In some languages, such as Python, there is no explicit superclass access operator, and ‘..’ is not used.Ellipsis
Ellipsis The ellipsis, denoted by three consecutive dots (…), is a punctuation mark that signifies an omission, a pause, or an unfinished thought. It serves a variety of functions in writing and can add depth, mystery, and intrigue to a piece. Functions: Omission: * Ellipses indicate that part of a quotation or text has been left out. * Example: “I cannot say what I have heard, but…” Pause: * Ellipses create a dramatic pause or moment of silence in the narrative. * Example: “He took a deep breath… and then he spoke.” Unfinished Thought: * Ellipses suggest that the speaker’s thought is incomplete or left unsaid. * Example: “I wonder if… if maybe…” Other Uses: Denoting Time: * In informal writing, ellipses can be used to represent the passage of time. * Example: “Monday… Tuesday… Wednesday…” Creating Suspense: * Ellipses can build suspense or tension by leaving the reader wondering what is going to happen next. * Example: “The monster crept closer… closer…” Adding Mystery: * Ellipses can evoke a sense of mystery or the unknown by abruptly breaking off a sentence or idea. * Example: “There was something strange about the house… something sinister…” Emphasizing a Point: * Ellipses can be used to emphasize a point by trailing off into silence. * Example: “I won’t say it again… you’re a fool.” Caution: While ellipses can be a powerful tool in writing, it is important to use them sparingly. Excessive use can disrupt the flow of the text and make it difficult to read. Additionally, ellipses should not be used to replace other forms of punctuation, such as commas or periods.
