To print lots of new lines with printf you can create a string that contains only new lines and use the width specifier to select how many you want. But you need to be careful not to print more than what's in the string.
#define new_lines "\n\n\n\n\n\n\n\n\n\n" assert( desired_new_lines <= sizeof( new_lines ) - 1 ); printf( "%.*s", desired_new_lines, new_lines );
