C# Params - Params Keyword in C#
- In C#, params is a keyword which is used to specify a parameter that takes variable number of arguments.
- It is useful when we don't know the number of arguments prior.
- Only one params keyword is allowed and no additional parameter is permitted after params keyword in a function declaration.

{
for (int i = 0; i < val.Length; i++)
{
Console.WriteLine(val[i]);
}
}
// Main function, execution entry point of the program
static void Main(string[] args)
{
Program program = new Program(); // Creating Object
program.Show(2, 4, 6, 8, 10, 12, 14); // Passing arguments of variable length
Console.ReadLine();
