The MathF.Pow() method in C# is used to compute a number raise to the power of another number.SyntaxFollowing is the syntax −public static float Pow (float val1, float val2);Above, val1 is the floating-point number raised to a power. The val2 parameter is the power or exponent.ExampleLet us now see an example to implement the MathF.Pow() method −using System; public class Demo {    public static void Main(){       float val1 = 5.00f;       float val2 = 3.00f;       Console.WriteLine("MathF.Pow() = "+MathF.Pow(val1, val2));    } }OutputThis will produce the following output −MathF.Pow() = 125ExampleLet us ...

To change the CursorSize of the Console in C#, use the Console.CursorSize property in C#.ExampleLet us see an example −using System; class Demo {    public static void Main (string[] args) {       Console.BackgroundColor = ConsoleColor.Blue;       Console.WriteLine("Background color changed = "+Console.BackgroundColor);       Console.ForegroundColor = ConsoleColor.Yellow;       Console.WriteLine("Foreground color changed = "+Console.ForegroundColor);       Console.CursorSize = 1;       Console.WriteLine("CursorSize = "+Console.CursorSize);    } }OutputThis will produce the following output −

To change the CursorLeft of the Console in C#, use the Console.CursorLeft property.ExampleLet us see an example −using System; class Demo {    public static void Main (string[] args) {       Console.BackgroundColor = ConsoleColor.Blue;       Console.WriteLine("Background color changed = "+Console.BackgroundColor);       Console.ForegroundColor = ConsoleColor.Yellow;       Console.WriteLine("Foreground color changed = "+Console.ForegroundColor);       Console.CursorLeft = 30;       Console.Write("CursorLeft position: "+Console.CursorLeft);    } }OutputThis will produce the following output −

To change the Foreground Color of text, use the Console.ForegroundColor property in C#.ExampleLet us see an example −using System; class Demo {    public static void Main (string[] args) {       Console.BackgroundColor = ConsoleColor.Blue;       Console.WriteLine("Background color changed = "+Console.BackgroundColor);       Console.ForegroundColor = ConsoleColor.Yellow;       Console.WriteLine("Foreground color changed = "+Console.ForegroundColor);    } }OutputThis will produce the following output −

To change the BufferWidth of the Console, use the Console.BufferWidth property.ExampleLet us now see an example −using System; class Demo {    public static void Main (string[] args){       Console.BufferHeight = 200;       Console.WriteLine("Buffer Height = "+Console.BufferHeight);       Console.BufferHeight = 250;       Console.WriteLine("Buffer Width = "+Console.BufferWidth);    } }OutputThis will produce the following output −Buffer Height = 200 Buffer Width = 200

The Char.IsLetter() method in C# is used to indicate whether the specified Unicode character is categorized as a Unicode letter.SyntaxFollowing is the syntax −public static bool IsLetter (char ch);Above, the parameter ch is the Unicode character to evaluate.ExampleLet us now see an example to implement the Char.IsLetter() method −using System; public class Demo {    public static void Main(){       bool res;       char val = 'K';       Console.WriteLine("Value = "+val);       res = Char.IsLetter(val);       Console.WriteLine("Is the value a letter? = "+res);    } }OutputThis will produce the following ...
