scanf() is an input function.
It takes an input from the user and store it in a variable.
Since "&" is a reference operator and it represents the memory location of the variable.
String is a type of array and an array consumes more than one memory address.
It is obvious that no need to use "&" operator for an entire array.
For an individual data type like int , char , float etc , "&" is needed but for an array no need to use "&".

By the way - it is not safe to pass strings to scanf() without doing bounds checking.

%c and %s are format characters used for input and output. These are mainly used in scanf and printf statements. %c is used for characters while %s is used for strings.

Why are strings on a squash racquet hollow?
There are no hollow core squash racket strings, though they do exist for tennis. There are two main types of string design in strings used for squash: monofilament & multifilament. Monofilament strings are a single solid material while multifilament strings are braided and have no central core. Monofilament strings tend to be more durable but typically transfer more shock to the arm while multifilament strings have a softer feel at impact and are closer in playability to natural gut.
