In my opinion, the string has many definitions,a group of objects that are connected with a string, wire, chain, etc. In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length changed, or it may be fixed . A string is generally understood as a data type and is often implemented as an array of bytes that stores a sequence of elements, typically characters, using some character encoding.
yes Henry, string has many definitions. simply, it is the sequence of characters. it may also contain spaces and numbers. Let me explain, the word "mango" and the phrase "I ate 2 mangoes" are both strings. I hope you get the idea
