In programming, strings are sequences of characters enclosed in quotation marks. They are used to represent text and allow manipulation of words, sentences, or any other textual information within a program.
Concatenation is the process of combining two or more strings together to create a new string. It allows you to join multiple pieces of text into one.
Indexing: Indexing refers to accessing individual characters within a string by their position. Each character in a string has an index number starting from 0 for the first character.
A substring is a smaller part of a larger string extracted based on its starting and ending positions. It allows you to extract specific portions from within a longer string for further processing.
