Here is the code:
#include
#include
#include

using namespace std;

int counter=0;

unsigned int getRandom(int nHigh, int nLow){
return (rand() % (nHigh – nLow + 1)) + nLow;
}
int main(){
int x, y;
x=1;
y=13;
int nGuess;

cout << "Enter a gues between 1 and 6: " <> nGuess;
getRandom(y,x);
if (nGuess < getRandom(y,x)){
cout << "too low try again" < getRandom(y,x)){
cout << "Too high try again" << endl;
counter=counter+1;
main();
}
else if (nGuess == getRandom(y,x)){
cout << "Congradulations!" << endl;
cout << "Number of Guesses: " << counter << endl;

}
system ("PAUSE");
return 0;
}

Anyway, I think this is a mistake:

“Second, the method by which the next number in the sequence shouldn’t be obvious or predictable.”

should be:

“Second, the method by which the next number in the sequence is generated shouldn’t be obvious or predictable.”

unsigned int GetRandomNumber(int nLow, int nHigh)
{
return (rand() % (nHigh - nLow + 1)) + nLow;
}

I don’t understand why those operations are being done to the random number. I also don’t get how using the modulus operator can change the maximum value for a random number (as in the first example: return nSeed % 32767;). Will someone explain please?

// If we’ve printed 5 numbers, start a new column

But actually, you’re starting a new row, not a new column.
