srand()

[makita18v]

So I've fixed pretty much all of my problems for my program which is supposed to seed the random number generator for rolling two dice. My program compiles, but I cannot get the random numbers to happen, and I've tried several different things. I've included all of my code, but really the only thing I can't get to work right is the random number generator, so any help would be great.

#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
const int SIX = 6; 

 using namespace std;
 int main ()
 {
	 int seed = (int)time(0);
	 srand(seed);
	 char gamePlay;
	 char playAgain;
	 char notAgain;
	 char yesSir;

	 cout << "Do you want to roll the dice?\n";
	 cout << "Enter y or n: ";
     cin >> gamePlay;
	 cin.ignore( 80, '\n' );
	switch (gamePlay)
	{
		case 'y':
		case 'Y':
			break;
		case 'n':
		case 'N':
			cout <<"Have a nice day." << endl;
		    system("PAUSE");
			return 'E';
		default:
			cout <<"Invalid input, please re-enter!" << endl;
			system("PAUSE");
			return 'E';
	}
		 do
		 {
			 int d1 = 1 + seed % SIX; 
		     int d2 = 1 + seed % SIX;
		     if (d1 == 6 && d2 == 6) 
			 	cout <<"You rolled boxcars\n";
			 if (d2 == 1 && d2 == 1) 
			 	 cout <<"You rolled snake-eyes\n";
			 else 
				cout <<"You rolled " << d1 << " and " << d2 <<endl;
				cout << "Do you want to play again?\n";
				cout <<"Enter y or n: ";
				cin >> yesSir;
				cin.ignore( 80, '\n');
				
			switch (yesSir)
			{
				case 'y':
				case 'Y':
					break;
				case 'n':
				case 'N':
					return 'N';
					break;
				default:
					cout <<"Invalid input, please re-enter!" << endl;
					system("PAUSE");
					return 'E';
			}

		 }while (yesSir != 'N');

	 system ("PAUSE");
	 return 0;

seed is not a random function. It is not a random number. seed is an int that you told to be the value of time(0).

To get random numbers, use the rand() function.

[Tassos Souris]

You can write this for example:

/* At the beginning of your program */
srand( (unsigned int)time( NULL ) );

/* more lines here */
int randomNumber = rand();

The above is how to combine the srand() and rand() functions.

To take a random number in the range of [ 1, 6 ]:

int dieFaceValue = 1 + rand() % 6;
