Constants in every language are the same. For example, in the C++ language some valid constant are: 53.7 , -44.4, +83.65, “Dinesh”, ‘M’, “2013” , “\n” etc. In C++ language constants are of two types: 1. Numeric Constant 2. Non-Numeric Constant (Character Constant) These ...

The enum type enables you to define named constants for integral built-in types (for example, int, uint, long, and so on). For more information, see enum. Constants must be initialized as they are declared. For example: class Calendar1 { public const int Months = 12; } C# Copy In ...
Unlike variables, constants never change in value. You must initialize a constant when it is created. C++ has two types of constants: literal and symbolic. A literal constant is a value typed directly into your program wherever it is needed. For example, consider the following statement: long...
In C# the #define preprocessor directive cannot be used to define constants in the way that is typically used in C and C++.To define constant values of integral types (int, byte, and so on) use an enumerated type. For more information, see enum.To...
In contrast, large integers and floating-point values (123,000,000, 3.14, or 0.000000871256, for example) require more storage space and more time for mathematical operations. By using the appropriate variable types, you ensure that your program runs as efficiently as possible. C's numeric ...
C# Constants - Learn about constants in C#, their types, and how to effectively use them in your programming projects.
In C# the #define preprocessor directive cannot be used to define constants in the way that is typically used in C and C++.To define constant values of integral types (int, byte, and so on) use an enumerated type. For more information, see enum (C# Reference).To...

Constants in C++ The first motivation forconstseems to have been to eliminate the use of preprocessor#definefor value substitution. It has since been put to use forpointers,function arguments,return types,class objectsandmember functions. (Page 334)...
