I'm rehashing some of the basics of c++ and I just want to find useful points along the way of things I can do to improve my coding.

This program has the user enter a number, then the computer try to guess it, with some higher/lower logic.

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

int main()
{
    srand(static_cast<unsigned int>(time(0)));  //seed random number generator

    int secretNumber = 0;
    int tries = 0;
    int guess;

    int highRange = 100;
    int lowRange = 0;

    std::cout << "\tWelcome to Guess My Number\n\n";

    std::cout << "\tPlease enter your number between 1 and 100:\n";

    std::cin >> secretNumber;

    do
    {
        do
            guess = rand() % highRange + 1;
        while (guess <= lowRange);

        ++tries;

        if (guess > secretNumber)
        {
            std::cout << "Computer guess was too high! (" << guess << ")\n\n";
            highRange = guess;
        }
        else if (guess < secretNumber)
        {
            std::cout << "Computer guess was too low! (" << guess << ")\n\n";
            lowRange = guess;
        }
        else
        {
            std::cout << "\nI guessed it! (" << guess << ") in " << tries << " guesses!\n";
        }

    } while (guess != secretNumber);

    return 0;
}
