Var vs const

Question

// can we write ?
const int x;
x=9;

Answer 1

No, this will give a compiler error. Constants in C# must be given a value when they are declared.

Answer 2

No, this will cause an error coz constant must be initialized with a value when declared nd it can't be changed, once it is assigned.

Answer 3

Just to add to what Lauren said.

Constant variables can not be changed during runtime of your program.

Answer 4

The difference between a constant and a variable is that a variable can change its value (like int x=5; some code x = 9.)
But a constant cannot be changed after you assign it to a value.
