在c ++中，改变光标位置而不使用窗口句柄。 Qbasic模仿慢 [英] in c++, changing cursor location without using the windows handle. Qbasic imitation is slow
问题描述
有时我需要在屏幕的某个位置写东西（例如：第10列和第20行）。我在网上搜索，发现它是使用Windows处理程序是使用windows.h。
是使用手柄快速但有点复杂，所以我写了一个类只使用printf（字符串），并以适合屏幕的方式更改字符串，每个printf命令填充整个80x24控制台屏幕。该类模仿QBasic的CLS，LOCATE x，y和PRINT命令。
问题：有一个更简单的方法来到达屏幕上的任何位置，并放置一个字符或点像我这样的慢类？
我的QBASIC类非常慢，我每秒只能使用几次。

delete mimic;

}
我认为没有解决方案。
void LOCATE （int x，int y）
{
COORD newPosition = {x，y};
HANDLE h = GetStdHandle（STD_OUTPUT_HANDLE）;
SetConsoleCursorPosition（h，newPosition）;
}
Sometimes i need to write things on a location of screen (ex: 10th column and 20th row). I searched on the net and found it is done with using windows handler which is using windows.h.
Yes, using handles are fast but somewhat complex so i wrote a class that uses only printf(string) and changes the string in a way that it fits to screen and every printf command fills the entire 80x24 console screen. The class imitates QBasic's CLS , LOCATE x,y and PRINT commands.
Question: Is there a simpler way to reach any location in screen and put a char or a dot(drawing) without using windows handle or a slow class like mine?
My QBASIC class is so slow that i can use it only several times per second. VC++ 10.0 windows XP
Thanks for your time.

delete mimic;
getchar();// waiting to see the screen before exiting. press enter to continue
return 0;
}
i think theres no solution.
Ok, I will continue using handles again.
void LOCATE(int x, int y)
{
COORD newPosition = { x, y };
HANDLE h = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleCursorPosition(h, newPosition);
}
