Create a program based on the attached 3 outputs below. Using a while loop is required in your program

Sample output 1:

Choices

E or e for Even

O or o for Odd

X or X for Exit

Enter your choices: e

.........This program is for Multiplication of even numbers........

Enter a number:20

1 * 2=2

2 * 4=8

3 * 6=18

4 * 8=32

5 * 10= 50

6 * 12=72

7 * 14=98

8 * 16=128

9 * 18=162

10 *20= 200

Sample output 2:

Choices

E or e for Even

O or o for Odd

X or X for Exit

Enter your choice:o

.....This program is for Multiplication of Odd numbers....

Enter a number:10

1 * 1=1

2 * 3=6

3 * 5=15

4 * 7=28

5 * 9=45

Sample output 3:

Choices

E or e for Even

O or o for Odd

X or X for Exit

Enter your choice:X

Your program will now exit.

The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by- letter basis in a very simple way. Tap code has been one of the most basic communication protocols and still used to convey SOS messages and other urgent communication. The tap code uses a 5×5 grid of letters representing all the English alphabets, see Figure 1. To communicate the word "water", the cipher would be the following (with the pause between each number in a pair being shorter (single space) than the pause between letters (two spaces)),

Your task is to design a program that can

i) convert any given string into a Tap code sequence

Prototype: char* convertToTapCode(char*)

ii) and A Tap code sequence to a string (char*)

Prototype: char* convertToString(char*)

Note: You are not authorized to use string data type; however, you can use char*

Addition of Big Integer

In this problem, you have to take two char arrays of numbers (e.g., “1203009954” and

“109876201453”) from the user and add these two numbers and store answer in a third char array digit by digit (“111079211407”).

char* additionOfBigInteger(char * Num1, char* Num2)

Subtraction of Big Integer

In this problem, you have to take two char arrays of numbers (e.g., and “1203009954”

“109876201453”) from the user and subtract these two numbers and store answer in a third char array digit by digit (“-108673191499”).

char* subtractionOfBigInteger(char * Num1, char* Num2)

Multiplication of Big Integer

In this problem, you have to take two char arrays of numbers (e.g., and “1203009954”

“109876201453”) from the user and multiply these two numbers and store answer in a third char array digit by digit (“132182164055668263162”).

char* multiplicationOfBigInteger(char * Num1, char* Num2)

Write a C++ recursive function PrintPattern1 to print following pattern using recursion. No

loops allowed whatsoever, and you can write other helping (recursive) functions. For example, calling your function with these argument PrintPattern1(1,10) should print following pattern. Your function prototype must be as follows:

void PrintPattern1(int start, int end);

pattern:
