What is difference between static and constant in C#? Constants are set at compile time itself and assigned for value types only. e.g. Static variable is a property of a Class rather than the instance of class. It is stored on the data segment area of memory and the same value is get shared to all instances of that class.

What is difference between static and readonly in C#?
Constant and ReadOnly keyword is used to make a field constant which value cannot be modified. The static keyword is used to make members static that can be shared by all the class objects.
What is static constant in C?
static const : “static const” is basically a combination of static(a storage specifier) and const(a type qualifier). Static : determines the lifetime and visibility/accessibility of the variable. When a variable is initialized using the const type qualifier, it will not accept further change in its value.
What is difference between static class and normal class?
A static class is similar to a class that is both abstract and sealed. The difference between a static class and a non-static class is that a static class cannot be instantiated or inherited and that all of the members of the class are static in nature.
What is difference between constant and readonly?
Difference between const and readonly
const fields has to be initialized while declaration only, while readonly fields can be initialized at declaration or in the constructor. const variables can declared in methods ,while readonly fields cannot be declared in methods.

What is difference between static variable and constant variable?
Static variables are common across all instances of a type. constant variables are specific to each individual instance of a type but their values are known and fixed at compile time and it cannot be changed at runtime. unlike constants, static variable values can be changed at runtime. Const means “cannot be changed.”
What are the types of constants in C#?
Types of Constant in C#

What is the difference between enum and #define constant in C?
18 Answers. enum defines a syntactical element. #define is a pre-preprocessor directive, executed before the compiler sees the code, and therefore is not a language element of C itself. Generally enums are preferred as they are type-safe and more easily discoverable.
What is final dart?
The final keyword in Dart is used to create constants or objects that are immutable in nature. The only difference between the final and const keyword is that final is a runtime-constant, which in turn means that its value can be assigned at runtime instead of the compile-time that we had for the const keyword.
What void means in C#?
The void keyword is used in method signatures to declare a method that does not return a value. A method declared with the void return type cannot provide any arguments to any return statements they contain.
