In data structures, a string is a sequence of characters used to represent text. Strings are commonly used for storing and manipulating textual data in computer programs. They can be manipulated using various operations like concatenation, substring extraction, and comparison.

String in Data Structure

String Data Type

In most programming languages, strings are treated as a distinct data type. This means that strings have their own set of operations and properties. They can be declared and manipulated using specific string-related functions and methods.

Note: In some languages, strings are implemented as arrays of characters, making them a derived data type.

String Operations

Strings support a wide range of operations, including concatenation, substring extraction, length calculation, and more. These operations allow developers to manipulate and process string data efficiently.

Below are fundamental operations commonly performed on strings in programming.

  • Concatenation: Combining two strings to create a new string.
  • Length: Determining the number of characters in a string.
  • Access: Accessing individual characters in a string by index.
  • Substring: Extracting a portion of a string.
  • Comparison: Comparing two strings to check for equality or order.
  • Search: Finding the position of a specific substring within a string.
  • Modification: Changing or replacing characters within a string.
