     You can think about structure as a list of fields (members). And each field has a specific type. It is possible the two (or all) of fields has the same type.

   • Data type in c++ or java for holding 20 digit integer

     Java specific:

     You are looking for BigInteger

     Immutable arbitrary-precision integers. All operations behave as if BigIntegers were represented in two's-complement notation (like Java's primitive integer types)

     For ex:

     BigInteger bint = new BigInteger("1234567856656569"); BigInteger bint2 = new BigInteger("1234556567856656569"); System.out.println(bint2.intValue()-bint.intValue()); //397189120-

     In java you can use:

     • [" BigInteger ",": for numbers without decimal values"]
     • [" BigDecimal ",": for numbers with decimal values"]

   • in C++, how do you code a class ADT--like std::vector or std::stack--that takes a data type in <> as argument and constructs the object accordingly?

     Top Answer

     Answered Mar 01, 2011 · 4 votes

     Let's say you have a class that implements your ADT using a hard-coded typedef T:

     class ADT{ public: typedef int T;- ADT(); T& operator[](size_t index); const T& operator[](size_t index) const; size_t size() const; ... private: T* p_; size_t size_;};

     (You have to work out the internal storage and member functions that are appropriate for your actual ADT).

     To change this so that you can specify T as done for std::vector etc.:

     template <typename T> <-- specification of T moved to hereclass ADT{ public: <-- typedef for T removed from here ADT(); T& operator[](size_t index); const T& operator[](size_t index) const; size_t size() const; ... private: T* p_; size_t size_;};

     Usage is then:

     ADT<int> an_adt_int;ADT<double> an_adt_double;-

   • Identifiers. A valid identifieris a sequence of one or more letters, digits, or underscore characters (_). Spaces, punctuation marks, and symbols cannot be part of an identifier.
   • Fundamental data types. The values of variables are stored somewhere in an unspecified location in the computer memory as zeros and ones. Our program does not need to know the exact location where a variable is stored; it can simply refer to it by its name.
   • Declaration of variables. C++ is a strongly-typed language, and requires every variable to be declared with its type before its first use. This informs the compiler the size to reserve in memory for the variable and how to interpret its value.
   • Initialization of variables. When the variables in the example above are declared, they have an undetermined value until they are assigned a value for the first time.

   What are the different data types in C?

   • In the C programming language, derived data types include functions, arrays, pointers, and references. An array, for example, is a derived data type since it comprises similar types of fundamental data types while also acting as a new data type in C.

   • Integers in C++, as in mathematics, are numbers such as 10,-12,45,98574,-765…. The boolean data type has only two values: true or false. The data type char is the smallest integral data type. The char data type is used to represent characters. Floating point data type deals with the decimal numbers. C++ provides three floating-point data types.
