Below is syntax of Scanf. It requires two arguments:
scanf("Format Specifier", Variable Address); Format Specifier: Type of value to expect while input Variable Address: &variable returns the variable's memory address.
In case of a string (character array), the variable itself points to the first element of the array in question. Thus, there is no need to use the ‘&’ operator to pass the address.
(Is Base address = address of first element)? 1
- ‘&’ is used to get the address of the variable. C does not have a string type, String is just an array of characters and an array variable stores the address of the first index location.
- By default the variable itself points to the base address and therefore to access base address of string, there is no need of adding an extra ‘&’
