/* The code will NOT compile in codeplayground :( This code shows sorting of numbers in ascending and descending orders visually (simple visual representation nothing fancy here). The code use classic bubble sort algorithm but can be easily adapted for other sorting algorithms. I was having trouble trying to adjust the drawing speed. Tried putting "sleep" call before clearing the screen and after drawing the screen without any luck so i left it and instead converted it into continuous ascending/descending sort, which was kind of interesting. Then last night a comment by Gordie led to futher discussion and ultimately resulting him (re)suggesting to alter the code sequence to get timing right(which i had tried earlier without success and forgotten). So i tried again and got it right this time. The difference between the earlier try and this time was the value passed to the sleep call. A value of less than 1 seems to make no difference to the output. But a value of 1 was good enough to slow down things to acceptable speed (for me). So Thanks to Gordie! :) */ #include #include #include using IV = std::vector ; auto Print = [](std::string const& title) { std::cout << title << "\n\n"; }; void Draw_vector_element(int indx, int ele) { std::cout << "iv[" << indx << "] = " << ele << " |"; for (int i = (0); i < ele; ++i) { std::cout << "__"; } std::cout << "\n"; } void Draw_vector(IV const &iv) { size_t idx{0}; for (auto i:iv) { Draw_vector_element(idx++,i); } std::cout << "\n"; } void sort_ascending(IV& iv) { size_t sz = iv.size(); for (size_t i(0); i < sz; ++i) for (size_t j(i+1); j < sz; ++j) { if (iv.at(i) > iv.at(j)) { system("clear"); std::swap(iv.at(i), iv.at(j)); Print("Sorting in ascending order using Bubble Sort"); Draw_vector(iv); sleep(1.0); } } } void sort_dscending(IV& iv) { size_t sz = iv.size(); for (size_t i(0); i < sz; ++i) for (size_t j(i+1); j < sz; ++j) { if (iv.at(i) < iv.at(j)) { system("clear"); std::swap(iv.at(i), iv.at(j)); Print("Sorting in descending order using Bubble Sort"); Draw_vector(iv); sleep(1.0); } } } int main() { IV iv{9,8,7,6,5,4,3,2,1}; Print("The initial state of the array"); Draw_vector(iv); Print("Press any key to start sorting"); getchar(); sleep(1); sort_ascending(iv); Print("Press any key to sort in reverse order now..."); getchar(); sort_dscending(iv); return 0; }
