我用turbo c2.01运行过，除了中文无法显示外，程序没问题。
你如果用visual c++运行的话中文应该能显示

到专业网站去吧

去www.csdn.net上面的C语言区发吧.那里会的并且乐于帮助的人很多.

main()
{
struct point a,b,c,n;
printf("Please input a point:");
get_point(&a);
printf("The Point you input is: ");
put_point(a);
printf("The area of triangle is:%f\n",triangle(a,b,c));
printf("输入平移向量坐标:");
get_point(&n);
a=add(a,n);
b=add(b,n);
c=add(c,n);
printf("平移后三角形面积为:%f",triangle(a,b,c));
}
