﻿ C# - Check If an integer is between 10 and 100 or 200

# C#: Check a given integer and return true if it is within 10 of 100 or 200

## C# Sharp Basic Algorithm: Exercise-4 with Solution

Write a C# Sharp program to check a given integer and return true if it is within 10 of 100 or 200.

Sample Solution:

C# Sharp Code:

``````using System;

// Namespace declaration
namespace exercises
{
// Class declaration
class Program
{
// Main method - entry point of the program
static void Main(string[] args)
{
// Calling the 'test' method and displaying the returned boolean values
Console.WriteLine(test(103));    // Output: True
Console.WriteLine(test(90));     // Output: True
Console.WriteLine(test(89));     // Output: False
Console.ReadLine();              // Keeping the console window open
}

// Method to check if a given integer is within 10 units of 100 or 200
public static bool test(int x)
{
// Checking if the absolute difference between 'x' and 100 is less than or equal to 10,
// OR the absolute difference between 'x' and 200 is less than or equal to 10.
// If either condition is true, returns true; otherwise, returns false.
if (Math.Abs(x - 100) <= 10 || Math.Abs(x - 200) <= 10)
return true;
return false;
}
}
}
```
```

Sample Output:

```True
True
False```
