Can't exit the while loop after guessing the right number

I'm trying to make a simple number guessing program with while loop but even after finding the right number (I changed the num with 5 and it didn't work) it does not exit the while loop. Can you tell me where the problem is?

int guess;
int num;

cout << "Enter the number (0-10): ";
cin >> guess;

while(guess != num){
    int num = rand()%10;
    cout << "Nope, keep trying." << endl;
    cout << "Enter the number (0-10): ";
    cin >> guess;
}

cout << "Congrats, you've found the number!" << endl;
