For your final project, you will be writing your own code to simulate the game battleship. More details will be forthcoming, but for today, you will have to write the function definition of the displayBoards function, which shows your board and your enemy's board, in the following style: 1 2 3 4 5 6 7 8 9 10 A | | | | | | | | | | | B | | | | | | | | | | | C | | | | | | | | | | | D | | | | | | | | | | | E | | | | | | | | | | | F | | | | | | | | | | | G | | | | | | | | | | | H | | | | | | | | | | | I | | | | | | | | | | | J | | | | | | | | | | | The two boards should appear side by side. void displayBoards(char [][10], char [][10]); Note:When you display the board, you are also displaying the contents of the 2D arrays, even though initially they will be empty.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."

For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.

What is a number system, and what is the total number of digits used in this system called? a number system is a system that uses different (options: a) numbers b) symbols c) codes d) digits e) alphabets) to represent different numbers. the total number of digits used in a number system is known as its (options: 1) processor 2) converter 3) radix 4) least significant digit 5) most significant digit)
