// Include C++ library definitions


#include <iostream> // For input and output
#include <string>   // To handle strings

using namespace std;

int main()
{

  string s1 = "Hello";
  string s2 = "Simon";
  string s3, s4, s5;

  // Assign and print out

  s3 = s2;
  cout << s3 << endl;

  // Compare

  if(s1 == s3){
    cout << "The same!" << endl;
  }
  else{
    cout << "Different!" << endl;
  }

  if(s1 < s2){
    cout << s1 << " is less than " << s2 << endl;
  }
  else{
    cout << s1 << " is not less than " << s2 << endl;
  }

  // Concatenation

  s3  = s1 + " ";
  s3 += s2;
  cout << s3 << endl;

  // Read in strings

  cout << "Type a string with spaces" << endl;
  getline(cin, s4);
  cout << "I have: " << s4 << endl;

  cout << "Type a string with a comma that ends with a period" << endl;
  getline(cin, s4, ',');
  getline(cin, s5, '.');
  cout << "I have: " << s4 << endl << s5 << endl;

  // Using a string as if it were an array

  s2[1] = 'u';
  cout << s2 << endl;

  for(int i = 4; i >= 0; i--){
    cout << s2[i];
  }

  cout << endl;

  // Member functions

  cout << "s3 is " << s3.size() << " characters  long" << endl;

  s3.replace(3, 2, "pp");
  cout << "After replacing, s3 is: " << s3 << endl;  
  
  s4 = s3.substr(6, 2);
  cout << "The substring is: " << s4 << endl;

  s3.erase();
  cout << "After erasing, s3 is: " << s3 << endl;
