getting error arithmetic operation resulted in an overflow in

## Understanding and Handling "Arithmetic operation resulted in an overflow" Error in C#nodejs
The "Arithmetic operation resulted in an overflow" error in C# (or any programming language) occurs when the result of an arithmetic operation (addition, subtraction, multiplication, division, etc.) exceeds the maximum or minimum value that a particular data type can hold. In simpler terms, you're trying to store a number that's too big (or too small) in a variable that can't accommodate it.

This error is a type of `OverflowException` and it's crucial to understand and handle it gracefully to prevent unexpected program behavior and crashes.

**1. Understanding Data Types and Their Limits**

Before diving into the error itself, it's vital to understand the limits of different data types in C#. Each data type (like `int`, `long`, `short`, `byte`, `decimal`, `float`, `double`, etc.) occupies a specific amount of memory and can therefore represent a specific range of values.

Here's a table summarizing common numeric data types in C# and their ranges:

| Data Type | Size (bits) | Range | Notes |
|-----------|-------------|-----------------------------------------------------------------|----------------------------------------------------------------------------------------------------------|
| `byte` | 8 | 0 to 255 | Represents unsigned 8-bit integers. |
| `sbyte` | 8 | -128 to 127 | Represents signed 8-bit integers. |
| `short` | 16 | -32,768 to 32,767 | Represents signed 16-bit integers. Also known as `Int16 ...
