Please help me urgently in C++
Question 1: Define a class called v which has the private data members length (oftype int), norm2 (of type float), and p a pointer (of type float). The class also has the member functions set(int), print0, gerNorm20, culate Norm20, a default parameterized constructor, and a destructor. Implement member functions. Use the following drive int main0 vector u: int ulength; cout Enter the vector length cin uLength: u set(uLength); u, print(); retum 0 Sample input output Enter the vector length 5 Enter 5 vector elements 4 7 9 2 8 The vector [4, 7, 9, 2, 8] has the norm 14.6287 Question 2: Add a destructor to the class and add the following code to the end of the above driver: vector v(u); print(); Sample input/output: Enter the vector length 5 Enter 5 vector elements 4 7 9 2 8 The vector [4, 7, 9, 2, 8] has the norm: 14.6287 The vector [4, 7, 9, 2, 8) has the norm: 14.6287 the 14.6287 The vector (7.17e 19e-e39 16887 e-039 9, 2, 81 has norm Question 3: Add a copy constructor to the class. Sample input output Enter the vector length: 5 Enter 5 vector elements 4 7 9 2 8 14.6287 The vector [4 7, 9, 2, 8) has the norm The vector [4 7, 9, 2, 8) has the norm: 14.6287 The vector [4, 7, 9, 2, 8] has the norm: 14.6287Explanation / Answer
