I have to produce a random number and can't figure it out. It gives me the same number each time. This isn't the homework. She told us how to produce the random number and i can't figure it out. The program I am writing for class is to learn how to use if statements.
I'm supposed to call srand once with a large prime number: srand(2707). Then it goes on to say that when you call srand with time as seed: srand(time(NULL)) the seed and the number will be different each time you run the program.
Here is the code that I have:
// I was told to include these three, should MAX_NUMBER be float?
void srand( unsigned int seed );
int rand ( void );
const float MAX_NUMBER = 20.0;
srand ( time( NULL ));
//I was also told to include this one.
number = int((float(rand() ) / float( RAND_MAX )) * MAX_NUMBER );
cout << number << endl;
