What is string

Answer 1

String is words.

okay that's oversimplified.

String is any cbination of letters, numbers or symbols in a variable.
so....

"he11o" is a string
"world" is also a string
"p@$W0rD" is again, a string.

a string is a variable that is different from Boolean and numerical variables. that's why you sometimes need to convert a string to numerical data, and vice versa.
