C++ program for selection sort. Here is the C++ program for sorting the integers in the list in ascending order using selection sort. This program does not move the nodes, just the integers.

We first create a linked list and then sort the integers in the list in ascending order using the selection sort algorithm. The selection sort algorithm is a simple sorting algorithm that works by selecting the smallest element from the unsorted list and swapping it with the leftmost unsorted element, and then moving the subarray boundaries one element to the right. The algorithm proceeds until the entire array is sorted. The program is as follows:```
#include
using namespace std;
struct node {
  int data;
  struct node *next;
};
void selection_sort(node *head) {
  node *i, *j, *min;

           min = j;
     }
     if (i != min) {
        temp = i->data;
        i->data = min->data;

The value of the result after the following Java statements execute is 9.

int a = 5;
int b = 4;
int result = a + b;Since we are adding the values of a and b, the value of result is 9 (5 + 4 = 9).

The given Java statements are as follows:int a = 3, b = 2, c = 1;int result = a * b - c / a;To determine the value of the result after the given Java statements execute, we need to follow the order of operations. The order of operations is a set of rules that dictate the order in which calculations should be done. The order of operations is as follows: Parentheses (including brackets and braces) Exponents

Multiplication and Division (from left to right) Addition and Subtraction (from left to right)Using the above order of operations, let's break down the given statement int result = a * b - c / a;: Multiplication (a * b): 3 * 2 = 6 Division (c / a): 1 / 3 = 0 (since c and a are both integers, so the result of division is an integer. So, we get the integer part of 0.3333..., which is 0.)Subtraction (a * b - c / a): 6 - 0 = 6

print(f"Paint cost: ${paint_cost_total:.2f}")

print(f"Sales tax: ${sales_tax:.2f}")

print(f"Total cost: ${total_cost:.2f}")

Explanation:

The input() function is used to read the wall height, wall width, and cost of one paint can as floats.

The wall area is calculated by multiplying the wall height and width, and then printed using formatted string literals to one decimal place.

The amount of paint needed is calculated by dividing the wall area by 350, the amount of square feet that one gallon of paint can cover. The result is printed to three decimal places.

The number of cans needed is calculated using the math.ceil() function to round up the value of paint_needed to the nearest integer.

The total cost of the paint is calculated by multiplying the cost of one paint can by the number of cans needed. The sales tax is calculated as 7% of the paint cost total. The total cost is calculated by adding the paint cost total and sales tax. All of these values are printed using formatted string literals to two decimal places.

Note: It's important to ensure that the input values are entered correctly, including the decimal points.

# Calculate the final grade

test_average = (test1_grade + test2_grade) / 2

quiz_average = (quiz1_grade + quiz2_grade + quiz3_grade) / 3

assignment_average = (assignment1_grade + assignment2_grade + assignment3_grade + assignment4_grade) / 4

project_average = (project1_grade + project2_grade) / 2

All of the statements you mentioned about the stack are true:

"Last in first out" (LIFO) means that the last item added to the stack is the first one to be removed.

The stack is a data structure that is implemented in memory, typically as an area of reserved memory. Option C

The stack is a fundamental data structure used in computer science and programming. It is a collection of elements, where the last element added is the first one to be removed, known as "last in, first out" (LIFO). This means that the stack behaves like a container of items that can be accessed in reverse order.

One of the key features of the stack is that it is implemented in memory. This means that the elements of the stack are stored in a contiguous block of memory, typically using an array or a linked list. The stack pointer is used to keep track of the top of the stack, which is the location of the most recently added item.

The stack is commonly used in computer programs for storing temporary data, such as function parameters, return addresses, and local variables. When a function is called, the parameters are pushed onto the stack, followed by the return address, and then the function's local variables. When the function returns, the stack is popped in reverse order, so that the local variables are removed first, followed by the return address and the parameters.

The stack is also used in many algorithms and data structures, such as depth-first search, postfix notation, and expression evaluation. In these cases, the stack is used to keep track of the order in which elements are processed.

In summary, the stack is a last in, first out data structure that is implemented in memory. It is a fundamental concept in computer science and programming, and is widely used in a variety of applications.
