2.12 LAB: Driving costs Driving is expensive. Write a program with a car's gas mileage (miles/gallon) and the cost of gas (dollars/gallon) as floating-point input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f' {your_value1:.2f} {your_value2:.2f} {your_value3:.2f}') Ex: If the input is: 20.0 3.1599 where the gas mileage is 20.0 miles/gallon and the cost of gas is $3.1599/gallon, the output is: 3.16 11.85 79.00 Note: Real per-mile cost would also include maintenance and depreciation. 401922.2754096 Aruy?

- 1.The following is the C code that you need to implement for this lab: uint8_ t f(uint8_tn) return(n<2)?(n):(f(n-1)+f(n-2)); The main function can be assumed as follows: int main() uint8_ t x; x=f(???); return 0; Obviously, " ? ? ? " is representing a value used to test the algorithm! Is "f"recursive? a.No answer text provided. b.Yes c.no d.depends on whether it is in for main 2.First, make the code in the previous question an actual C program so that it can be compiled and it runs. Play with it so that you feel comfortable with the logic of the code. Then implement the code in TTPASM. Note that you need to preserve the actual C code structure, this means you cannot it into a non-recursive subroutine. Furthermoreall conventions discussed in class regarding subroutines must be followed. The idea is that I should be able to substitute f with my own code, and main should work. Or, I can substitute main with my own, and f should work. Attach the source code of your assembly…I need a memory diagram of this C++ function: ***CODE*** #include using namespace std; int f2(int r, int& s) { r /= 2; s *= 3; int temp = r + s + 20; return temp; } int f1(int& p) { int q = 5; p = 95; int temp = f2(p, q); return temp; } struct s1 { string fname; int grade; s1() : fname(""), grade(0) {} }; int main() { int a = 7; int b = f1(a); s1* summa_cum_laude = new s1(); s1* magna_cum_laude = new s1(); summa_cum_laude->fname = "Roxanne"; summa_cum_laude->grade = a; magna_cum_laude->fname = "Rock"; magna_cum_laude->grade = b; cout << (*summa_cum_laude).fname << "'s grade: " << (*summa_cum_laude).grade << endl; cout << (*magna_cum_laude).fname << "'s grade: " << (*magna_cum_laude).grade << endl; delete summa_cum_laude; magna_cum_laude = nullptr; }The language we are using here is in Racket. Please enter the following code: (cond ((equal? 16 3) (+ 3 8)) ((equal? 16 8) 12) (else (* 6 3))) Write the return value for the above code. If replacing all of the 16's in the above code with 8, what is the return value? What about replacing the 16’s with 3? What does the cond function do?
- Question Asked Jul 9, 2020 3 views Python Programming- Computer-Assisted Instruction Part 1: Computer-Assisted Instruction (CAI) refers to the use of computers in education. Write a script to help an elementary school student learn multiplication. Create a function that randomly generates and returns a tuple of two positive one-digit integers. Use that function's result in your script to prompt the user with a question, such as: How much is 6 times 7? For a correct answer, display the message "Very good!" and ask another multiplication question. For an incorrect answer, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. Then, modify the program so that various comments are displayed for each answer. Possible responses to a correct answer should include 'Very good!' , 'Nice work!' and 'Keep up the good work!'

- I). Write a program in c++ with class that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.Complete the following questions about different types of variables:i. Check the last digit of your id number(123456789). If it is even or 0, fill the gap in (A)with the word global (i.e., static global), otherwise, fill it with local (i.e., static local).Then, complete Table I. ii. In a multi-source program, there is a fileA.c that contains variables and functions,and a fileB.c that contains the main function, as well as usage of some of theresources found in fileA.c. Explain:a) fileA.c has a global variable called my_variable, that should only beaccessed within the file. I.e., no other files should be able to access thatvariable.How should my_variable be declared inside of the file, in order to guaranteethis functionality? b) fileA.c also has a global variable called my_shared_variable, which canand should be accessible from other files, including fileB.c.How should my_shared_variable be declared in order to allow thisfunctionality?Note for item ii): You also need to state in a…1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.
