Output the elements from index n to the last index of the vector, where n is specified by the vector's last element. End each number with a newline. Ex: If the input is 7 12 18 2 0, the vector's last element is 2. Thus, the output is: 18 2 Note: The input has at least three integers, and the vector's last element is always less than the vector's size. #include <iostream>#include <vector>using namespace std; int main() { vector<int> intVect; int value; int i; int n; cin >> value; while (value != 0) { intVect.push_back(value); cin >> value; } // insert code here return 0;}

The sum of each row, each column, and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one-dimensional parallel arrays of integer type. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. See the sample outputs for more clarification.
