Can anyone help, I need to randomly output for example

1
2
3
4
5
6
 
  possible sentences that will output: (///no limit and all random each time

   How are you? What's your name? what day is it? etc

Single sentences not all three, but different each time :)


This code will be in a loop which will break after outputting, and when its called again its expected to be random!!!


I am not asking to display randomly generatd sentneces, but instead sentences which I made previously to be randomly outputted.

You can use random number generator with rand()(http://www.cplusplus.com/reference/cstdlib/rand/ ) function and an array of strings which will store your possible snetences. Then you just generate random number and print the string with index of this number from the array.

   vector<string> sentences = { "Great Expectations", "A Tale of Two Cities", "Hard Times",
                          "The Old Curiosity Shop", "Oliver Twist", "Martin Chuzzlewit",
                          "Pickwick Papers", "David Copperfield", "Dombey and Son",
                          "A Christmas Carol" };

   int size = sentences.size();
   string dummy;
   srand( time( 0 ) );
   cout << "Keep pressing enter\n";
   while ( getline( cin, dummy ) ) cout << sentences[rand()%size] << '\n';
}
