Question: c im trying to read a file of integers into...

C++: I'm trying to read a file of integers into an array in c++. I can't use vectors and the file size could change. I had attempted to create a function to open the file once and get the count of items in the file then initialize the array to store the data in main with that number, however C++ won't let me unless it's a constant value. What is the best way to read data from a file into an array if the size is not given? Examples are greatly appreciated.
