Here I have created the function named removeOdds(). In this method, I have iterated over the elements of the vector. Next, I have checked if the element is odd or not. If the element is odd then I have removed it from the vector using erase() method. If the element is not odd then I have incremented the pointer to next index. C++ code: #include <vector> #include <algorithm> #include <iostream> #include <cassert> using namespace std; void removeOdds(vector<int> &v) { auto index = v.begin(); while (index != v.end()) // iterating over the vector { if (*index % 2 == 1) // if the element at index is odd then erase it v.erase(index); else ++index; // if element is not odd then increment the index } } void test() { int a[8] = {2, 8, 5, 6, 7, 3, 4, 1}; vector<int> x(a, a + 8); assert(x.size() == 8 && x.front() == 2 && x.back() == 1); removeOdds(x); assert(x.size() == 4); sort(x.begin(), x.end()); int expect[4] = {2, 4, 6, 8}; for (int k = 0; k < 4; k++) assert(x[k] == expect[k]); } int main() { test(); cout << "Passed" << endl; } Screenshot of the output: Hope it helps!!

Concept explainers

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Please write the code for the removeOdds function using vectors. Will thumbs up if correct!

```cpp
// b. Implement the removeOdds function :
#include <vector>
#include <algorithm>
#include <iostream>
#include <cassert>
using namespace std;

// Remove the odd integers from v. It is acceptable if the order of
// the remaining even integers is not the same as in the original vector.
void removeOdds(vector<int>& v)
{
// Function body to be implemented
}

void test()
{
int a[8] = { 2, 8, 5, 6, 7, 3, 4, 1 };
vector<int> x(a, a + 8); // construct x from the array
assert(x.size() == 8 && x.front() == 2 && x.back() == 1);
removeOdds(x);
assert(x.size() == 4);
sort(x.begin(), x.end());
int expect[4] = { 2, 4, 6, 8 };
for (int k = 0; k < 4; k++)

}

int main()
{
test();
cout << "Passed" << endl;
}
```

**Explanation:**

This C++ program template is designed to demonstrate how to remove odd integers from a vector. The key components of the code include the implementation of a test function and the declaration of the `removeOdds` function, which currently lacks a functional body. Once implemented, the `removeOdds` function should filter out odd numbers from the passed vector.

- **Libraries Included:**
- `<vector>`: For using the `vector` data structure.
- `<algorithm>`: For utility functions like `sort`.
- `<iostream>`: For input and output operations.
- `<cassert>`: For checking assertions during testing.

- **removeOdds Function:**
- This function is declared to remove odd elements from a vector passed by reference. The function body is currently a placeholder and must be implemented.

- **test Function:**
- A predefined array of integers is converted into a vector.
- An assertion checks the initial conditions of the vector (`size`, `front`, and `back`).
- The `removeOdds` function is called on the vector.
- After odds are removed, the vector is checked again for expected conditions — both `size` and contents.
- The vector is sorted to help verify that

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.

Answer in C++ code please! (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its push_back function to add each unique value to the vector.

1) Define a global variable Emps that is an array of pointers to employee structs. 2) Change your createEmployee function to add the new employee to the Emps array. It should place it in the first slot that contains a NULL. 3) Write a listEmployees function that will call your display function on each employee in the array. 4) Change main to have a loop that looks for user commands. • If the user types HIRE, you should call createEmployee. If the user types LIST, you should call listEmployees. • If the user types QUIT, you should exit the loop, which will then cause the program to exit. 5) Write a findEmployee function that takes a string parameter and returns the employee pointer with that name or NULL if no such person exists. Change main to add a FIND name command that will find and display a single employee.
