Using switch statement write a menu driven program to overload a function series as follows:

(a) void series() — To find and display the sum of the following series:
    S = 2 - 4 + 6 - 8 + 10 ….. - 20

(b) void series(int n, int x) — To find and display the sum of the following series:
    S = (x² / 1!) + (x⁴ / 3!) + (x⁶ / 5!) + ……. to n terms

Method which reverses a given number is:

1. Impure method
2. Pure method
3. Constructor
4. Destructor

Design a class to overload a function series( ) as follows:

(a) void series (int x, int n) – To display the sum of the series given below:

x¹ + x² + x³ + ………. xⁿ terms

(b) void series (int p) – To display the following series:

0, 7, 26, 63 ………. p terms

(c) void series () – To display the sum of the series given below:

1/2 + 1/3 + 1/4 + ………. 1/10

Define a class to overload the method display() as follows:

void display(): To print the following format using nested loop.

1 2 1 2 1
1 2 1 2 1
1 2 1 2 1

void display (int n, int m) : To print the quotient of the division of m and n if m is greater than n otherwise print the sum of twice n and thrice m.

double display (double a, double b, double c) — to print the value of z where

$z = p \times q$

$p = \dfrac{a + b}{c}$

$q = a + b + c$
