Also, mein Programm sieht jetzt so aus:
| C++: |
#include <iostream>
#include <sstream>
void clear_screen(std::ostream& out)
{
out<<"\x1b[2J"<<std::flush;
}
void set_point(std::ostream& out, unsigned x, unsigned y)
{
out<<"\x1b["<<x<<";"<<y<<"HX"<<std::flush;
}
void draw_line(std::ostream &out, int x1, int y1, int x2, int y2) {
if(x1 == x2 && y1 == y2)
set_point(out, x1, y1);
else {
double
dx = double(x2 - x1) / std::max(std::abs(x2 - x1), std::abs(y2 - y1)),
dy = double(y2 - y1) / std::max(std::abs(x2 - x1), std::abs(y2 - y1)),
rx = x1,
ry = y1;
while(unsigned(rx + .5) != x2 || unsigned(ry + .5) != y2) {
set_point(out, unsigned(rx + .5), unsigned(ry + .5));
rx += dx;
ry += dy;
}
set_point(out, x2, y2);
}
}
int main(int argc, char *argv[]) {
int a, b, c, d;
sscanf(argv[1], "%d", &a);
sscanf(argv[2], "%d", &b);
sscanf(argv[3], "%d", &c);
sscanf(argv[4], "%d", &d);
clear_screen(std::cout);
draw_line(std::cout, a, b, c, d);
}

und läuft einwandfrei.
