c++ - How to use carriage return with multiple line?

Question

When I want to print out another text in the same line, I can do this:

int i = 0;
string text = "Paragraph ";
while (i < 10) {
    if (clock() % CLOCKS_PER_SEC == 0) {
        cout << text << i + 1 << "
";
        cout.flush();
        i++;
    }
}

But, how I can I do this with multiple line? I want to retain a paragraph as a whole in its initial position in terminal. If I change text with a string that contains paragraph with some newline characters, it prints another new block of paragraph below the last printed.

How can I retain it's position?

Answer 1

Your question isn't very clear, but I'm going to assume you want to know how to overwrite text in places other than the current line.

Standard C++ doesn't give you this capability. You will have to use OS-specific functionality to place the cursor at an arbitrary place of the console.

Under Unix-like systems you will generally use ANSI escape sequences

Under Windows you're best served by the console manipulation functions, in particular SetConsoleCursorPosition. Look here for more console functions.
