See also string (C++). In modern standard C++, a string literal such as "hello" still denotes a NUL-terminated array of characters. In C++ there is a primitive string type and also a standard string class (used above). For character strings, the standard library uses the convention that strings are null-terminated: a string of n characters is represented as an array of n. An array is defined as finite ordered collection of homogenous data, stored in contiguous memory locations. The delimiter can be one of the following punctuation marks: The delimiter can be one of the following punctuation marks: The returned string contains the delimiter specified by the first character in string2 added to make string1 a valid delimited identifier. But the fundamental difference between character array and string is that the “character array” can not be operated with standard operators, whereas, the “string “objects can be operated with standard operators.
