class point_3d
{
int x,y,z;
public:
point_3d (int x1,int y1,int z1)
{
x=x1,y=y1,z=z1;
}
point_3d operator +(point_3d p)
{
point_3d temp;
temp.x=x+p.x;
temp.y=y+p.y;
temp.z=z+p.z;
return temp;
}
void show()
{
cout<<x<<y<<z<<endl;
}
};
void main()
{
point_3d p1(1,2,3),p2(5,4,3),p3;
p1.show();
p2.show();
getch();

Answer 2

Because Turbo C++ has syntax which is no longer supported in later versions of the C++ standard, i.e. Turbo C++ is growing obsolete.

Some difference include:
- Main function must be int and returns 0 at the end of your program.
- Header files such as <iostream.h> has been renamed to <iostream> .
