     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-

     And BigDecimal

     In java you can use:

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

   • Data type of character constants in C and C++

     In C, data type of character constants is int, but in C++, data type of same is char.  If we save below program as test.c then we get 4 as output (assuming size of integer is 4 bytes) and if we save the same program as test.cpp then we get 1(assuming size of char is 1 byte) 

     C++

     // C++ program demonstrating that data type of character// constants in C++ is same as 'char' #include <iostream>using namespace std; int main() {     cout << sizeof('a');     return 0;} // This code is contributed by sarajadhav12052009-

     C

     #include <stdio.h>int main(){  printf("%lu", sizeof('a'));     getchar();  return 0;} -

     Output of C++ program:

     1

     Output of C program:

   Mar 5, 2023 · Enumeration in C++. Last Updated : 05 Mar, 2023. Enumeration (Enumerated type) is a user-defined data type that can be assigned some limited values. These values are defined by the programmer at the time of declaring the enumerated type.

   An enumeration is a user-defined data type that consists of integral constants. To define an enumeration, keyword enum is used. enum season { spring, summer, autumn, winter }; Here, the name of the enumeration is season. And, spring, summer and winter are values of type season.

   • Unscoped Enumerations
   • Notes
   • Defect Reports

   Each enumerator becomes a named constant of the enumeration's type (that is, name), visible in the enclosing scope, and can be used whenever constants are required. Each enumerator is associated with a value of the underlying type. When initializers are provided in the enumerator-list, the values of enumerators are defined by those initializers. If...

   Values of unscoped enumeration type can be promoted or convertedto integral types: Values of integer, floating-point, and enumeration types can be converted to any enumeration type by using static_cast. Note that the value after such conversion may not necessarily equal any of the named enumerators defined for the enumeration:

   13. You are looking for strongly typed enumerations, a feature available in the C++11 standard. It turns enumerations into classes with scope values.

   An enum is a special type that represents a group of constants (unchangeable values). To create an enum, use the enum keyword, followed by the name of the enum, and separate the enum items with a comma: enum Level { LOW, MEDIUM, HIGH. }; Note that the last item does not need a comma.

   May 16, 2024 · Declarations. [edit] An enumerated type is a distinct type whose value is a value of its underlying type (see below), which includes the values of explicitly named constants ( enumeration constants ). Syntax. Enumerated type is declared using the following enumeration specifier as the type-specifier in the declaration grammar :

   What is enumeration in C & C++?

   • An enumeration provides context to describe a range of values that are represented as named constants. These named constants are also called enumerators. In the original C and C++ enum types, the unqualified enumerators are visible throughout the scope in which the enum is declared.

   What is the difference between C and C++ enum types?

   • In the original C and C++ enum types, the unqualified enumerators are visible throughout the scope in which the enum is declared. In scoped enums, the enumerator name must be qualified by the enum type name. The following example demonstrates this basic difference between the two kinds of enums:
