Clear screen

[sandeep1]

Hi,
I am writing a OOP program which create menu using cout. I am not using MFC or
graphic programming. Just simple standard OOP C++ language. Once I select option# from my menu, it will create sub-menu. But the problem is I want to clear the screen from standard output and then sub-menu should written to standard output. I tried but I could not find a key which will clear the standard output. Any suggestions?

Thanks,

Sandeep

For a quick screen clear, you could output sufficient new lines to scroll any text off the console window...

Otherwise, have a look at the Console Functions such as
ScrollConsoleScreenBuffer, FillConsoleOutputCharacter, etc.

for a normal console app, you can use

System ("cls");

The Alternative which is better than A System Command or Outputting lines is to use old fashioned Escape characters like 27 73

Another easy way is :

int main()
{
cout << "the command bellow gonna clear the screen, let's try this...";
cout << "\x1b[2J"; // CLEAR SCREEN

// You need to path ansi.sys into your config.sys (and the \x1b[2J gonna do job
}
