#### What is string manipulation in computer science?

String manipulation refers to the process of modifying, manipulating, and extracting information from strings in computer programs. In computer science, a string is a sequence of characters that represents text or other data.

#### What are some common string manipulation techniques?

Some common string manipulation techniques include concatenation, substring extraction, string length, string search, and string modification. These techniques allow programmers to extract useful information from strings, manipulate and transform strings as needed, and perform various string-related operations efficiently.

#### How do you concatenate strings in programming languages?

Concatenation is typically done using the "+" operator in programming languages. For example, to concatenate two strings "hello" and "world" in Python, you can use the following code: "hello" + "world".

#### What is substring extraction in string manipulation?

Substring extraction is the process of extracting a portion of a string. This is typically done using the substring() method in programming languages. For example, to extract the substring "world" from the string "hello world" in Java, you can use the following code: "hello world".substring(6, 11).

#### Why is string manipulation important in computer science?

String manipulation is important in computer science because strings are used extensively in many applications, such as text processing, web development, and data analysis. The ability to manipulate and transform strings efficiently is a critical skill for programmers who work with text data, as it allows them to extract useful information from strings, manipulate and transform strings as needed, and perform various string-related operations efficiently.
