Complete the following program skeleton so it displays the volume of a cylindrical fuel tank. The formula for the volume of a cylinder is Volume = πr2h whereπ is 3.14159r is the radius of the tank h is the height of the tank#include <iostream> #include <cmath>int main() {  double volume, radius, height;  cout << "This program will tell you the volume of\n";  cout << "a cylinder-shaped fuel tank.\n";  cout << "How tall is the tank? "; cin >> height;  cout << "What is the radius of the tank? "; cin >> radius;  // You must complete the program. return 0;}

#include using namespace std; Type the program's output int main() { int g; g = 3; while (g <= 5) { } cout << g << endl; g = g + 1; return 0;

THIS IS FOR C++ ONLY Part 2b: Password Verification A secure password is critically important in today's world. Organizations typically have stringent requirements to ensure a password is complex enough so as not to be easily hacked. Write a program that will accept as input a potential password and determine whether or not it is valid in meeting the following criteria: at least eight characters long at least one uppercase letter at least one lowercase letter at least one digit at least one special character (you can determine what is acceptable) If the password is valid, ask the user to enter it again. If it matches, indicate the password has been accepted. If the password does not meet any of the above criteria, indicate which it does not meet.
