Question

Task 1

Please generate a vector of the following values:

12,32,33,44

and assign this vector to a variable x.

Then extract the first element and the last element from this vector

Answer 1

#include <bits/stdc++.h>
using namespace std;

int main()
{
   vector<int> x;
   int n, inp;
   cin >> n; // number of input
   while(n--){
       cin >> inp; // give input
       x.push_back(inp);
   }

   cout << " first element : " << x[0] << endl;
   cout << " last element : " << x[x.size() -1] ;

   return 0;
}

Answer 2

# Create vector x with values 12, 32, 33, 44
x <- c(12, 32, 33, 44)

# Extract first and last elements
first_element <- x[1]
last_element <- x[length(x)]

# Print results
cat("Vector x:", x, "\n")
cat("First element:", first_element, "\n")
cat("Last element:", last_element, "\n")

Output :-

Vector x: 12 32 33 44 

First element: 12 

Last element: 44
