Strings

You have been using strings. What are they?

In coding, a string is a piece of text - like a word or a sentence.

It is called a string because each letter or character follows on from the next. Imagine the letters hanging on a piece of string!

Usually, strings have double or single quote marks around them, like this:

"The quick brown fox"
'jumped over the lazy dog.'

Definitions

String

A sequence of characters, one after another - "The fox"

Strings can hold just one character - "£"

Strings can even be empty - "".

Character

A letter of the alphabet - a, b, c, A, B, C, …

or a digit - 0, 1, 2, …

Any other symbol on the computer - space , percent %, an emoji 🤗, …

Concatenation

Concatenation is joining strings

It is performed the + operator.

"The quick brown fox" + " " + "jumped over the lazy dog."
= "The quick brown fox jumped over the lazy dog."
