ROS determines the size of an array itself? Really
Following the ros code in ros msg format:
Ephemeris[] eph
which is equivalent of this in c:
Ephemeris *eph;
Now I have heard that ros determines itself the size of an array. One does not have to give it size.
Now for the C code inorder for me to iterate in the array I need to know the size of the array but I believe in ros, I dont.
So if I am writing a C code and I want to access the msg format and I want to iterate through the array eph, how can I do it without knowing the size of eph
