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

$z = p \times q$

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

$q = a + b + c$

Invoking a method by passing the objects of a class is termed as:

1. Call by reference
2. Call by value
3. Call by method
4. Call by constructor

Define a class to overload the method perform as follows:

double perform (double r, double h) — to calculate and return the value of curved surface area of cone

$CSA = \pi rl \quad l = \sqrt{r^2 + h^2}$

void perform (int r, int c) — Use NESTED FOR LOOP to generate the following format

r = 4, c = 5

output
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

void perform (int m, int n, char ch) — to print the quotient of the division of m and n if ch is Q else print the remainder of the division of m and n if ch is R
