none of this is changing the end result is there something wrong with my formula?

Ok, try this:

 

where you have

 

cout << fortunes[number];

 

try putting in ths:

 

cout << fortunes[0];
cout << fortunes[1];
cout << fortunes[2];
cout << fortunes[3];

 

Just make sure your strings are stored the way you think they are. If running that spits all four variables in order like you typed them, then you're good.

 

Also...

 

I don't think this is right

 

(rand() % 4)

 

As far as I know, rand() should return a decimal between 0 and 1. So if you want it to give you 0,1,2,or 3, shouldn't it be (rand() * 3)?

 

Try putting a cout statement in there to spit out the random number after it's generated and run it a few times to make sure your randoms are what you want.

 

See a pattern here?

 

Just start adding cout statements everywhere. That's how I debug. Make sure things are how you think they are every step of the way. Doing this works with any program.

using

(rand() * 3); gives me a error in windows??????????

 

 

Ok I dont think I did the string right because when I change

 

cout << fortunes[number]

to

cout << fortunes[2]

 

it still prints out the same one as before and that is the last one in the string...

 

ok when using an array like that I have to declare it outside of the main function???

 

 

 

WOOOOOOOOTTTTTTTTTT IT WORKS. All I had to do what move

 

stirng fortunes[4] = ....

 

outside the main function and it works.

 

WOW so simple

 

Here is complete code

#include <iostream>
#include <string.h>
#include <stdlib.h>
using namespace std;

string fortunes[4] = {"Only Death Awaits you", "Your 1337ness is a inspiration", "On the binary finger shirt everyone is giving you 00000100", "Watch out for that car"};

int main()
{ 
   srand(time(NULL));
   
   cout << "Press any button to reveal your fortune....(wooo mystical)\n\n";
   system ("pause");
   
   cout << "\n";
   cout << "Your Fortune is.....\n\t";
   
   int number = (rand() % 4);
   
   cout << fortunes[number];
   
   return 0;
   
}

EDIT:

 

I installed DevCPP, couldn't help it

 

Ok, the random number line you had was right. This gives me 0-3 as output

 

number = rand() % 4;

 

 

However,

 

   
cout << fortunes[0] << "\n";
cout << fortunes[1] << "\n";
cout << fortunes[2] << "\n";
cout << fortunes[3] << "\n";

 

Gives the same output four times, so the way you're population your array of strings is not working, I think.

 

EDIT EDIT#

 

This should work:

 

#include <iostream>
#include <string>
//#include <stdlib>
using namespace std;

int main()
{
  srand(time(NULL));
  
  int number;
  string fortunes[4] = {"Only Death Awaits you", "Your 1337ness is a inspiration", "On the binary finger shirt everyone is giving you 00000100", "Watch out for that car"};
  
  cout << "Press any button to reveal your fortune....(wooo mystical)\n\n";
  system ("pause");
  
  cout << "\n";
  cout << "Your Fortune is.....\n\t";
  
  number = rand() % 4;
  
  cout << fortunes[number] << "\n";

  system ("pause");
  
  return 0;
  
}

 

When you declare and populate your array of strings, you need to use "{" and "}", not "(" and ")".

ok ignore my edits then cause your right about the {}, but I triend them earlier and they didnt work....???..... neways I got it to work go back to page one to read my excitment....

[Verran]

Glad it's working now, but moving that declaration outside the main function.... I don't think that's making any difference. The reason it's working now is because of the curly brackets {}.

[Archerzz]

Now I need to think of another program to write...
