Constants

In this example, we’re declaring a constant named MAX_VALUE of type int and initializing it with the value 100. Once a constant has been declared and initialized, its value cannot be changed.

Constants can be useful in situations where you have a value that should never change, such as a mathematical constant like pi (π) or the speed of light (c). By using a constant instead of a variable, you can help prevent accidental changes to the value.

One important thing to note about constants is that they must be initialized with a value at the time they are declared. You cannot declare a constant and then assign a value to it later.

Here are a few more tips for using constants in your C# code:

• Use all capital letters and underscores to separate words in the constant name. This helps make it clear that the value is a constant and not a variable.
• Use constants for values that are used multiple times in your code. This can help make your code more readable and easier to maintain.
• Be careful not to use constants excessively. Overuse of constants can make your code harder to read and understand, especially if the constant names are not descriptive.
