Clearing output of a terminal program in Linux C

Question

I want to clear the output of a C program produced with printf statements. I want to clear only one line, for example:

[source]

printf(\"AAAAAAAAAAAAAA\\         


        

Answer 1

There're several ways to delete the DDDDDDDDDDDDDD

1. Print backspace several times

printf("\b");

2. Print carriage-return and then print something to override the original line

printf("\r");

3. If you are in a newline. You may use terminal commands to move your cursor

such as printf("\033[8;5Hhello"); // Move to (8, 5) and output hello

Other commands:

printf("\033[XA"); // Move up X lines;
printf("\033[XB"); // Move down X lines;
printf("\033[XC"); // Move right X column;
printf("\033[XD"); // Move left X column;
printf("\033[2J"); // Clear screen
...

4. Don't forget ncurses

It is the best ways to control the exact layout and format in a terminal
