How do we write the io_display function in ONE line only?
void io_display(const char *str, int row, int col, int len) {
io_move(row, col);
if( len <= 0)
io_putstr(str);
else {
for(;len>0; len--) io_putch(*str ? *str++ : ' ' );
}
}
Well, use the same logic, the code can change as below:
void io_display(const char *str, int row, int col, int len) {
for((io_move(row, col), (len <= 0)?io_putstr(str):0); len>0; len--)
io_putch(*str ? *str++ : ' ' );
}
