Multiple choice

Assume that you just opened a new R session. If you execute the following codes one by one (from the top to the bottom), which ones of these would successfully create a vector? There is at least one option which will create a vector successfully, but there might be multiple. If so, you must select all of the ones.

Options
A.v1<-c(1,2,3)
B.v2<-c("a","b","c")
C.v3<-c(max(v1),min(v1))
D.v4<-c(1,TRUE)
E.v5<-c(a)
F.v6<-c(1,"2")

Step-by-Step Analysis
In this R session scenario, we evaluate which assignments would successfully create a vector when executed in order. Option 1: v1<-c(1,2,3). This uses c() to combine three numeric literals, producing a numeric vector of length 3. Since there are no conflicting typ......Login to view full explanation

Question textWrite the implementation of the function template compare_vectors. int compare_first_n_values(const vector<T> &vector1 , const vector<T> &vector2, int n) This function receives the following parameters: A reference to a constant vector of type T. A reference to a constant vector of type T. An int value with the number of values to compare (starting from the first position). The function compares the first n values of the vectors, returning the number of equal values. This function does a memberwise comparison (vector1.at(0) == vector2.at(0), vector1.at(1) == vector2.at(1), ..... , vector1.at(n-1) == vector2.at(n-1)). The function must return -1 if the value of n is greater than the size of any of the vectors. NOTES: You can safely assume that the input is always correct. You must use the function identifier from the specifications of the question when writing your solution. You do not need to write a main function. Solutions not compiling will receive a 100 % penalty. Hardcoding the output will translate into a 100 % penalty. For example:[table] Test | Result vector<string> string_vector1 {"Carlos", "Alberto", "Rincon", "Castro"}; vector<string> string_vector2 {"Edmundo", "Jose", "Rincon", "Castro", "Urdaneta"}; cout << compare_first_n_values(string_vector1, string_vector2,4) << endl; | 2 [/table] Answer:(penalty regime: 0 %)template <typename T> int compare_first_n_values(const std::vector<T>& vector1, const std::vector<T>& vector2, int n) { if (n > vector1.size() || n > vector2.size()) { return -1; 1234567template <typename T>int compare_first_n_values(const std::vector<T>& vector1, const std::vector<T>& vector2, int n) { if (n > vector1.size() || n > vector2.size()) { return -1; ההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Check Question 2

Question textWrite a C++ function that counts how many integers in a vector<int> contain at least one occurrence of the digit given as a parameter. For example, given the following integer vector, and the function call: vector<int> numbers = {1234,4355,6541,8976};int result = count_numbers_with_digit(numbers,4); The returned integer value must be 3 (The values in the vector with at least one 4 are: 1234, 4355, and 6541). The function's header is as follows: int count_numbers_with_digit(const vector<int> & numbers, int digit) This function takes as parameters a vector<int> containing positive integers greater than zero, and a single-digit positive integer representing the digit to find in each number stored in the vector. Notes: You can safely assume that the input is always valid. You do not need to write the main function. A 100% penalty will be applied to solutions that do not compile. A 100% penalty will be applied to solutions that hardcode the output. For example:[table] Test | Result vector<int> numbers = {1234,4355,6541,8976}; int result = count_numbers_with_digit(numbers,4); if (result == 3) { cout << "Correct implementation of the count_numbers_with_digit user-defined function" << endl; } else { cout << "Incorrect implementation of the count_numbers_with_digit user-defined function" << endl; cout << "Returned value: " << result << endl; cout << "Correct value: 3" << endl; } | Correct implementation of the count_numbers_with_digit user-defined function [/table] Answer:(penalty regime: 0 %)#ifndef FUNCTIONS_H #define FUNCTIONS_H #include <iostream> using namespace std; // Write the definition and implementation of the count_numbers_with_digit user-defined function here int count_numbers_with_digit(const vector<int> & numbers, int digit) { int count = 0; for (size_t i = 0; i < numbers.size(); ++i) { int num = numbers[i]; int d = digit; do { if (num % 10 == d) { ++count; break; } num /= 10; } while (num > 0); } return count; } #endif 1234567891011121314151617181920212223242526272829#ifndef FUNCTIONS_H#define FUNCTIONS_H#include <iostream>using namespace std;// Write the definition and implementation of the count_numbers_with_digit user-defined function hereint count_numbers_with_digit(const vector<int> & numbers, int digit){ int count = 0; int count = 0; for (size_t i = 0; i < numbers.size(); ++i) { int num = numbers[i]; int d = digit; do { if (num % 10 == d) { ++count; break; } num /= 10; } while (num > 0); } return count;}#endif ההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Check Question 2
