When passing an array as an argument to a function, say, print_foo,
where the function isn't meant to modify the array, it makes perfect
sense to me to make it a const.
But what about when passing structs, ints, bools, etc? If the function
doesn't need to modify them, what's the standard practice?
I guess an example. (hopefully if I've ERRORED, my intent is still
clear)
struct foo
{
int x;
int y;
};
void init(foo &p, const int x, const int y)
{
p.x = x;
p.y = y;
}
Do people do that in practice? Is it good practice?
It feels a little ridiculous to do
void foo_exit(const bool valid)
{
if(!valid)
exit(1);
exit(0);
}
yet
void init(foo &p, const int x, const int y)
{
if(x = 0)
do_something_cool();
p.x = x;
p.y = y;
}
