How does the addch waddch and mvwaddch work?

The addch, waddch, mvaddch and mvwaddch routines put the character ch into the given window at its current window position, which is then advanced. They are analogous to putchar in stdio (3). If the advance is at the right margin, the cursor automatically wraps to the beginning of the next line.

What are the coordinates of the screen in ncurses?

The first thing to know about ncurses is that screen coordinates are row,col, and start in the upper-left at 0,0. ncurses defines two global variables to help you identify the screen size: LINES is the number of lines on the screen, and COLS is the number of columns. The bottom-right position is LINES-1,COLS-1.
