re-coding the code. HLEP!!

[Sprinkles]

hello, i have a long code and i want to re-code it without using <ctime> library. the code is about reading array from file and write it to other file.
i know that <ctime> is to generate random numbers. however, i want it to read from file with my own values knowing that the first 3 numbers (start point), second (target point) and the rest are (obstecles). i'm so sorry the code is too long. the code is working but not the way i want it to.

If you want people to take the time and effort to read large amounts of code, you'll want to use code tags to format it properly:

You don't need to use the <ctime> library for generating random numbers. Use the standard way.

Generating 5 random numbers 1 - 100. (obviously pseudo)

#include <iostream>
#include <random>
#include <chrono>
#include <functional>

int main()
{
    std::mt19937::result_type seed =
    std::chrono::high_resolution_clock::now().time_since_epoch().count();

    auto get_rand =
    std::bind(std::uniform_int_distribution<int>(1, 100), std::mt19937(seed));

    for (unsigned short int n = 0; n != 5; ++n)
    {
        std::cout << get_rand() << "  " << std::flush;
    }

    std::cin.get();

    return 0;
}
