a.
Passing parameters by value:
While passing the parameters by value, a copy of that parameter is made and it is passed to the function. The value of parameter is copied to another location of memory. The location of memory where original value is saved remains intact.
Passing parameters by reference:
While passing parameters by reference, the address of value at which it is stored in memory is passed to the function. The original value of parameter changes during execution of a function.

- C++ Using Card and Deck class created during the lecture or your own implementation that follows the spec for a card and deck, implement the following game: game is designed for a single player who is playing against the computeryou draw three cards for each player (player and a computer) Using the compare function from the Card class you compare each pair drawnIf the player's card is higher, the player gets a pointYou repeat this comparison 3 times (for each pair of cards you draw)The player wins if he gets more points than a computer (has more higher cards than the computer)arrow_forwardCode using c++ 2. Solving a Person's Loneliness by CodeChum Admin It's been 1,245 years and our sole Person is getting lonelier each day. This Person definitely needs a partner! Thus, we need to update our Person's design to have a gender as well and there shall be male and female! Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. Your task is to first update the struct Person so that it can have a gender as well. For this program, we shall represent a gender with a single character: 'M' for male and 'F' for female. Then, create a Person, take in an integer user input and a character user input, and then set them as the Person's age and gender respectively. Finally, call the displayPerson() function and pass that Person you created. Input 1. The age of the Person 2.…arrow_forwardExercise 3.

Thanks. Suppose a loan has a face value of $1,000, the annual interest rate is 15%, and the duration is 18 months. The interest-to-be-paid is computed by multiplying the face value of $1,000 by 0.15, yielding $150. That figure is then multiplied by the loan period of 1.5 years to yield $225 as the total interest owed. That amount is immediately deducted from the face value, leaving the consumer with only $775 (i.e. $1000 - $225). Repayment is made in equal monthly installments based on the face value (i.e. $1000 in this case). So the monthly loan payment will be $1,000 divided by 18, which is $55.56. This method of calculation may be alright if the client needs $775, but the…arrow_forward
- Can you help me with this question?arrow_forwardIN C++ This is a simulated chess game. With this project, I want you to move all the pieces on one side of the board. First: If you are unsure how the pieces of a chess board move, do some research. There is plenty of information out there to instruct how a chessboard functions. Your chess piece movement must follow the rules of the game. Second: This is a one-sided board and used to illustrate how each piece moves. Third: The program must keep track of the location of each piece. By this I mean that if a piece is moving, it must respect the position of the other pieces on the board. Fourth: With each move the user should also be given the option to start a new game or end the program.arrow_forwardC++ OOP use classes only...arrow_forward
