Can I return the count of an array?

[Mesvak]

Hi,

I have this code which takes in a file, reads it in as a binary array,
and prints the array.

Is there anyway I can write a code which would print the number of
binary values taken and printed? like a counter? So basically if a
file consists of 10529 bits... I want it to print that value also. Any
suggestions?
Code:
void dBinary(unsigne d);

int main()
{
char filename[60];
cout << "Please enter the filename you wish to use to embed: \n";
cin >filename;

ifstream in;
in.open(filenam e, ios::in);
char ch;

// Assign each byte to ch
// and then pass it to the function dBinary
while (in.get(ch)) {
dBinary(ch);
}

in.close();
cout << endl << endl << endl;
return 0;
}

void dBinary(unsigne d u)
{
register int b;

for (b = 128; b 0; b = b/2) {
(u & b) ? (cout << '1') : (cout << '0');
}
}
Thanks in advance for your help.

You probably mean bytes, not bits. No modern architecture could possibly
hold a file that contains exactly 10529 bits.

Since this is C++, use std::vector.

Code:
void dBinary(unsigne d);

std::vector<uns ignedmyArray;

Your homework assignment is to write the code for dBinary that adds a new
element to myArray. Then, the number of elements read is simply:

myArray.size();

What happens if the user writes more than 59 characters? ("But I am
the only one who is going to use this." Fine, but you can make a mistake
too.)

What's wrong with using std::string?

ifstream in;
in.open(filenam e, ios::in);

Nitpicking, but given that ios::in is the default for std::ifstream,
you don't have to specify it. Besides, you can open the name in the
constructor:

std::ifstream in(filename);
