Example of Varaible Number of Arguments in function. Addition function with variable number of arguments

/**
 * To learn about variable number of arguments to the function
 * The three dots ( ... ) are used in a function's declaration as a parameter.
 * These dots allow zero to multiple arguments to be passed when the function is called.
 * The three dots are also known as var args .
 * Varargs is a short name for variable arguments.
