A string is a sequence of characters, like letters, numbers, or symbols, that are grouped together. It's essentially a piece of text.
String manipulation refers to changing, combining, or extracting parts of a string to modify its content. It's like playing with words or sentences to make them say what you want. For example, you can change the order of words, add new words, or remove some words from a sentence. In programming, string manipulation involves operations like finding the length of a string, converting it to uppercase or lowercase, replacing certain words or characters, splitting it into smaller parts, and joining different strings together. It's all about working with text to make it do what you need it to do in your program.
