Random number generator help

Hey I am currently trying to write a program that has the user enter a value and then this becomes the max value for the generator. So if the user enters 10 the generator picks a number between 1 and 10. The next step is the user has to guess the value the generator picks. My problem lies in every time I use the number 10 as the maximum value the generator always picks the number 8. I need help trying to figure out how to make the maximum value 10 and then have the generator pick different values every run through. The number 8 the first run through, the number 2 through the 2nd run through and the number 6 on the first run through. These previous numbers are made up and the program doesn't have to run any of these previous picked numbers just in case I wasn't clear early. Any help would be appreciated. Thank you.
Code:

```#include <iostream> #include <stdio.h> #include <stdlib.h> #include <time.h> using namespace std; int main () {         int x,guess;         cout << "Enter a maximum value" <<endl;         cin >> x;         cout << "Your number is between 0 and "<< x << endl;         x = rand()%(x + 1);         srand(time(NULL));                 cout << "Enter your guess" <<endl;         cin >> guess;         while ( guess != x)         {                                 cin >> guess;                                 if (guess > x)                 {                         cout << "Guess lower" <<endl;                 }                 else if ( guess < x )                 {                         cout << "Guess higher" <<endl;                 }                 else                 {                         cout << "Congratulations you guessed the correct value" << endl;                 }         }                                 system("PAUSE");         return 0; }```

Re: Random number generator help

reverse this 2 lines
from
Quote:
 x = rand()%(x + 1); srand(time(NULL));
to
Code:

```    srand(time(NULL));     x = rand()%x + 1;```

thank you so much I didn't even think about reordering the lines.
