Question
Let's say you initialize x as "uint32_t x = 0x0000FFFF;". What is the value of (x << 1)?
Expert Solution
arrow_forward
Explaination
1) initial value of uint32_t x = 0x0000FFFF
2) Now in expression (x << 1) we are shifting value of x to right side 1 times
3) Value of x can be written as below
0x0000FFFF = 0000 0000 0000 0000 1111 1111 1111 1111
4) Shifting it right by 1 is
0000 0000 0000 0001 1111 1111 1111 1110 = 0x0001FFFE
5) so after shifting by 1 we get value of expression (x << 1) as 0x0001FFFE

- Suppose the Great Frederick Fair wants to update its ticketing software. They need you to write a program to handle the price calculations, using the rules*: ● The basic price of a ticket is $40. Senior citizens (age >= 65) get a 50% discount. Children under 6 are free (100% discount). For residents of Frederick County, the basic price is $35; the same discounts still apply. So the individual ticket prices range from $0 to $40. ● . Your program should request age and county name from the user. The age will be entered as an integer and the county name as a string. Before calculating the price, confirm that the user's age is valid - not negative and not more than 110. If it is not, give a message and do not do the price calculation. Also, the county name should not be case sensitive - for example, Frederick, frederick, and FREDERICK should all be acceptable. Your program should then calculate and print out the ticket price, using the appropriate discounts. Test your program with a…arrow_forwardIn city street grids, intersections are often defined by two integers, counting the position of horizontal and vertical streets (sometimes called streets and avenues). Imagine traveling from position (h₁, ₁) to (h₂, v₂). How many blocks do you traverse? (h₂, v₂) (h₁, v₂) Even though there are many possible routes, the distance only depends on the differences h₂ h₁ and v₂ - ₁. However, you need to take the absolute value because the differences might be negative. Complete the following program that prints the number of blocks traveled, given the origin and destination of the trip (which will change as your code is tested). #include 3 4 using namespace std; 5 6 int main() 7 { 8 9 10 11 12 13 5555555 14 15 16 17 18 19 int h1; int v1; int h2; int v2; cin >> h1; cin >> v1; cin >> h2; cin >> v2; /* Your code goes here */ cout << "Distance: << distance << endl;arrow_forwardHow do I write a game program that throws a die (singular for dice) until a certain number appears a given number of times in a row? A random die number can be generated with the following code: int diceFaceNumber = (int)((Math.random() * 6) + 1). There are two versions of the output. The first traces the program as it throws the dice and the other version just prints the number of throws it took. The game should first prompt the client for a die face number he would like to appear in a row. Then the program prompts the client for the number of times he would like that die face number to appear that many times in a row. The game then throws the die until that die face number appears that many times in a row. The game reports the number of throws it took to get that die face number to appear the requested number of times in a row. Allow the client to repeat the game as many times as she wishes. There are several methods that I can use: one public method that is invoked from the main, a…arrow_forward
- First, write code that uses scnr.nextInt() to read in a value for numTomatoes from input. Then, write code that uses System.out.println() to output "My recipe needs ", the variable numTomatoes, and " tomatoes." Ex: If the input is 5, then the output is: My recipe needs 5 tomatoes. Ex: If the input is 3, then the output is: My recipe needs 3 tomatoes.arrow_forwardIn Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.arrow_forwardin Java eclipse ide Read from console a 2-digit integer number, save it in variable vz. Check this number: if the digit at 10’s place is greater than the digit at 1’s place, swap these 2 digits to construct a new number, then save this new number to vz. For example, if the original number in vz is 65, swap 2 digits and vz will change to 56; if the original number is 34, vz will not change. (Clue: extract digits at 10’s place and 1’s place, compare these 2 digits to determine if these 2 digits need to be swapped or not)arrow_forward
