table length

[bbone]

Hi!

I have a problem with computing the length of a table. Let's say, i have a table like this:
double table[] = {..some elements..}
I use sizeof(table)/sizeof(double) and it works fine in main function. But when i use it in some other function, that has table for parameter, it always returns 0.
Why?
Thanks

you can only save this size in some variable:
int len;//where will be the size
double *table = new double[len];

by the way, use vectors:
vector<double> x;
double y = sommething;
x.push;
x.push(y + 1);
cout<< x.size()<< endl;

What returns 0?

Neither sizeof(table) nor sizeof(double) can be 0.
Consequently sizeof(table)/sizeof(double) can't be 0 either.

Instead of implementing your own table, use vector or other collections in STL.
