To change the BufferHeight of the Console, use the Console.BufferHeight property in C#.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);    } }OutputThis will produce the following output −Buffer Height = 200

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

The MathF.Exp() method in C# returns the raised to the specified power.SyntaxFollowing is the syntax −public static float Exp (float val);Above, Val is the floating-point number.ExampleLet us now see an example to implement the MathF.Exp() method −using System; class Demo {    public static void Main(){       float val = 90f;       float res = MathF.Exp(val);       Console.WriteLine("MathF.Exp() = "+res);    } }OutputThis will produce the following output −MathF.Exp() = InfinityExampleLet us now see another example to implement the MathF.Exp() method −using System; class Demo {    public static void Main(){       ...
