You can use the ncurses library to do this. The downside to this solution is that you won't be able to use cout for outputting anymore.
您可以使用 ncurses 库来执行此操作。此解决方案的缺点是您将无法再使用 cout 进行输出。
#include <ncurses.h>
int main()
{
initscr();
printw("Press Any Key To Exit...");
getch();
endwin();
}
Be sure to -lncurseswhen compiling
