#include <iostream>

#include <string>

using namespace std;

int main () {

  // Creating variables

  int myNum = 5;               // Integer (whole number)

  float myFloatNum = 5.99;     // Floating point number

  double myDoubleNum = 9.98;   // Floating point number

  char myLetter = 'D';         // Character

  bool myBoolean = true;       // Boolean

  string myString = "Hello";   // String

  // Print variable values

  cout << "int: " << myNum << "\n";

  cout << "float: " << myFloatNum << "\n";

  cout << "double: " << myDoubleNum << "\n";

  cout << "char: " << myLetter << "\n";

  cout << "bool: " << myBoolean << "\n";

  cout << "string: " << myString << "\n";

  return 0;
