Thread: about reading character from a file

If you would like to read a certain number of charectors or an entire line you can use fgets.

Code:

char String[256];
FILE *input = fopen(FileName, "r");

fgets(String, 256, input);

This will get at most 256 charectors from input and store the char array to String. If fgets incounters a new line ('\n') it stops and stores what it has taken to String. If you want to only get 4 char then just change 256 to 4.

If you're doing encryption, you'll probably be doing decrpytion in the same prog, and for that I expect you'll need to read in binary mode (depending on how you've encrypted the data). For that you'll need fread() and fwrite().

Also,

Code:

while(file.get(fp) == NULL)

this is C++, not C. If you're coding C++, best post you're code questions in the C++ forum
