Thx for the advice. really helpful. I just knew about default operator =
assignment.
Anyway, programming 101:
i have this kind of loop
for(int k = 0; k<10; k++)
{
Vertex3 v1(0, 0, k);
//process v1 here
}
and another version (but same function)
Vertex3 v1
for(int k = 0; k<10; k++)
{
v1.set(0, 0, k);
//process v1 here
}
I have no intention to store v1. I just want to process it and get the process
result.
Is the second one more efficient than the second one?
When I construct an object with same variable more than once, does it create 10
object or it just replace the first one?
Thanks
