Is it a good practice to pass struct object as parameter to a function in c++?
- by tsubasa
I tried an example live below:
typedef struct point
{
int x;
int y;
} point;
void cp(point p)
{
cout<<p.x<<endl;
cout<<p.y<<endl;
}
int main()
{
point p1;
p1.x=1;
p1.y=2;
cp(p1);
}
The result thats printed out is:
1
2
which is what I expected. My question is: Does parameter p get the full copy of object p1? If so, I wonder if this is a good practice? (I assumed when the struct gets big in size, this will create a lot of copy overhead).
