same random number, how do I make them different?

[LDgaming]

My random seed keeps giving me the same value for both random numbers. How can I change my code so the random values aren't always equal to each other? When I have the user input the data the program runs fine but I can't get the program to solve itself because it always gets the answer on the first try.

 #include <cstdlib>
#include <ctime>
#include <iostream>

using namespace std;

int randRange (int low, int high)
{
    srand ( time( NULL ) );
    return rand () % ( high - low + 1) + low;
}
int randguess (int low, int high)
{
    srand ( time( NULL ) );
    return rand () % ( high - low + 1) + low;
}


int main ()
{
    cout << "Please pick a number between 1 and 100: \n";
    int answer;
    answer = randRange ( 1, 100 );
    int guess = randguess ( 1, 100);
    int guess_low = 1;
    int guess_high = 100;

    for ( int i = 0; i < 10; i++ )
    {
        if ( guess < answer )
        {
            cout << "Your guess is too low: \n";
            cout << guess;
            guess_low = guess;
            guess = randRange (guess_low, guess_high);
        }
        if ( guess > answer )
        {
            cout << "Your guess is too high: \n";
            cout << guess;
            guess_high = guess;
            guess = randRange (guess_low, guess_high);
        }
        if ( guess == answer)
        {
            cout << "YAY! You got the answer!";
            cout << guess;
            break;
        }
    }
}

Thank you for the help. It seems that my error was that I was using srand() twice and that was causing it to use the same number when I needed to use srand once.
