[j-lee00]

In C how would i create, open and write an array to a text file

The array is EeV[i],

does it make a difference if im using ubuntu or windows

fopen() to open the file fwrite() to dump the data fread() to get it back.
The only differenc eon windows is you have to add a 'b' in the fopen() call to specify binary, ie fopen(filename,"wb") to open a file for writing.

I like to create a memory block containing all the data and the file header, and then just write the whole block to my hard drive.
