In several situations, you may have to flush the unwanted buffer in order to get the next input in the preferred container. That is, not in the previous variable buffer. Let us consider a situation where after encountering the statement “cin”, the user has to input a string or character...
I realized it is because when I enter the string for area, the last character ENTER gets stored in stdin buffer and is treated as the value for sex. To make the program function as expected, I have to insert another scanf("%c", &sex") between the two do-while loops...
//Tangiable software converter C++ TO C# CONVERTER TODO TASK: The cout 'flush' manipulator is not converted by C++ to C# Converter: //ORIGINAL LINE: std::cout <<"Au to Us: $"< Console.Write("Au to Us: $"); string buffer = Console.ReadLine(); HoursWorked = Convert.ToDoubl...
but you'll probably want toflush()manually on interactive problems. Further I/O optimizations are possible (see comments section), but this is the major one and is sufficient for contests.
I have MDI MFC application. I have added command line support in this.If I run this application through command prompt, I did not get any output on command prompt.I want to see output on command promt, what to use to get output there. How can I get output on command prompt....
FlushConsoleInputBuffer(GetStdHandle(STD_INPUT_HANDLE)); char buffer[1]; DWORD read; ReadConsoleA(GetStdHandle(STD_INPUT_HANDLE), buffer, sizeof(buffer), &read, NULL); SetConsoleMode(GetStdHandle(STD_INPUT_HANDLE), oldMode); CloseHandle(GetStdHandle(STD_INPUT_HANDLE)); ...
I've never seen it done that way before but I don't see a manual flush at all. The following function may or may not result in the phrase being printed to the console. There is no flush. std::cout <<"hello world\n"; Whenever you fail to implement a manual flush you can't cont...
obtained when it is in this state. So the state is reset to good using .clear(). However the invalid entered chars which caused the cin >> extraction to fail are still in the input buffer and have to be removed - otherwise the cin >> would immediately fail again - an infinite loop!
