- a- Consider the following program written in C syntax:void swap(int a, int b) {int temp;temp = a;a = b;b = temp;}void main() {int value = 2, list[5] = {1, 3, 5, 7, 9}; swap( value, list [0]);swap( list [0], list [1]);swap(value, list[value]);}For each of the following parameter-passing methods, what are all of the values of the variablesvalue and list after each of the three calls to swap? 1. Passed by value2. Passed by reference3. Passed by resultint p =5 , q =6; void foo ( int b , int c ) { b = 2 * c ; p = p + c ; c = 1 + p ; q = q * 2; print ( b + c ); } main () { foo (p , q ); print p , q ; } Explain and print the output of the above code when the parameters to the foo function are passed by value. Explain and print the output of the above code when the parameters to the foo function are passed by reference. Explain and print the output of the above code when the parameters to the foo function are passed by value result. Explain and print the output of the above code when the parameters to the foo function are passed by name.12) Consider the following function: def squareArea(sideLength) : return sideLength ** 2 What is the value of squareArea(3)? _____ a.2 b.3 c.6 d.9
- In C++ Please Modify the program 8-31 from page 584, 585 by adding the following: 1. Add a prototype before main() like: void bubbleSort(Circle [], int); 2. On line 21 add the following function call: bubbleSort(circle, SIZE); 3. After main() function add the definition for bublleSort() function similar to the one on page 628. Evidently you must change the Inventory data type with Circle. The example in the textbook displays all the areas in order because the input is such that will cause the in order output. Your program should display all circles in order even when the input for radii is not in any particular order. // This program uses an array of objects. // The objects are instances of the Circle class. #include <iostream> #include <iomanip> #include "Circle.h" // Circle class declaration file using namespace std; const int NUM_CIRCLES = 4; int main() { Circle circle[NUM_CIRCLES]; // Define an array of Circle objects // Use a loop to initialize the radius of each…Write C assignment statements for the following: a. Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.10 How do I write "Minesweeper" in C# with the following requirements ?1. This will be played in the console2. The game should be able to randomly generate 10 mines in a 10x10 grid3. The user will be able to enter a command that represents a coordinate to check a location for a mine4. The application will display a number from 0-8 depending on how many mines surround that location* If the user selects a mine, the game will respond "boom!" and the game will be lost* If every non-mine square has been revealed, the game is won

The enum Scoops will have 3 data values: single, double, and tripple. Define variables needed for customer name, ice cream flavor, and number of scoops. Reads the value of the customer name, ice cream, and number of scoops from the user. Use a switch statement and the following price chart to determine the price: 1 scope = $3.75 2 scopes = $5.50 3 scopes = $7.20 Prints customer name, price of order based on scoop, and flavor of ice cream ordered.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.
- 1. Inspect the code and in your own interpretation, describe the reason call to functionChangeIt_1(n) will not change x in main()? 2. Inspect the code and in your own interpretation, describe the reason parameter n inChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? 3. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 4. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.Question 40. Consider the following code chunk: import random x=0while(x < 4): x = random.choice([1, 2, 3]) print(x) It is not a good idea to run these lines because...a) x is an invalid argument to print().b) the condition x < 4 is never violated.c) the function random.choice() does not exist. d) x is initialised with the wrong type.code a simple code using C to produce the following command.
