A char is a type of data in computer programming that is used to store and represent a single character. A character can be any letter, number, symbol or even a space. Think of it like a little box that can hold just one letter or symbol at a time.
For example, let's say your name is Sally. Each letter in Sally's name can be stored in a separate char box. So, the first char box holds 'S', the second holds 'a', the third holds 'l' and so on.
Char boxes can also be used together to create words, sentences, and even whole paragraphs. For instance, "Hello, World!" can be stored as a series of char boxes. Each letter or symbol has its own char box that together make up the message.
In summary, a char is a small storage container for a single letter or symbol in computer programming. It's like a building block for creating words, sentences, and more complex messages.
