Reading a large file into an Array.
Posted on 2002-07-22
I'm having a problem figuring out how to read a large file from disk into an array. The way I know of doing this is to do a byte by byte read of the file and filling the array. This takes quite a bit of time as the file's I'm reading are generally in the 15Mbyte range. The hex bytes are read into the array and then the contents are analyzed. Also, I would like to read a word at a time, but the bytes are reversed when I read them. As an example, if I was reading the word 4E6F hex, the word read comes out 6F4E. How do I fix this big indian, little indian problem so I can read from the file directly into the array without transposing the digits.
I'm using Visual C++ on a PC.
