10. Create a function based on the following information:
Your mission is to encrypt a secret message (text only, without special chars like "!", "&", "?" etc.) using Caesar cipher where each letter of input text is replaced by another that stands at a fixed distance. For example ("a b c", 3) == "d e f"
Input: A secret message as a string (lowercase letters only and white spaces) and number to move text
Output: The same string, but encrypted
Return: The same string, but encrypted
Laboratory Practice Task 5.5:
Write a program that solves quadratic equation of the form
ax2 + bx + c
where a, band c are constant coefficients. Quadratic equation has two roots and they
can be computed using the following formulas:
root1 = -b + vb²- 4ac
2a
root2 = -b - vb² - 4ac

- 6.22 C++ Define a function named SwapValues that takes four integers as parameters and swaps the first with the second, and the third with the fourth values. Then write a main program that reads four integers from input and calls function SwapValues() to swap the input values. The main program then prints the swapped values on a single line separated with spaces and ending with a newline. The program must define and call the following function:void SwapValues(int& userVal1, int& userVal2, int& userVal3, int& userVal4) Ex: If the input is: 3 8 2 4 function SwapValues() stores 8, 3, 4, and 2 in userVal1, userVal2, userVal3, and userVal4, respectively.

The player selects one of the options listed in a console prompt, then the computer randomly selects an option as well. The winner of the game is determined as follows: Rock beats Scissors - Scissors beats Paper - Paper beats Rock The same selection results in a tie. Your program must do the following: Prompt the player to enter a selection in the console. Provide instructions to user on what is a valid input. For example, you can have the integers 1, 2, and 3 represent the selection, or use the words rock, paper, scissors, etc. Check that the user entered valid input. If the entry is invalid, the program needs to inform the user of the invalid input and can end, or re-prompt the user for their entry. Generate a random selection for the computer's choice.
