Answer 1

For Unix(-based), use ioctl(2) and TIOCGWINSZ:

#include  //ioctl() and TIOCGWINSZ
#include  // for STDOUT_FILENO
// ...

struct winsize size;
ioctl(STDOUT_FILENO, TIOCGWINSZ, &size);

/* size.ws_row is the number of rows, size.ws_col is the number of columns. */

// ...

Also, while I haven't touched Windows in the last five years, GetConsoleScreenBufferInfo() should help you get the console window size.
