Read file by bits c++
18,801
You can't just read file bit by bit. So, you should use something like this:
ifstream f(inFile, ios::binary | ios::in);
char c;
while (f.get(c))
{
for (int i = 7; i >= 0; i--) // or (int i = 0; i < 8; i++) if you want reverse bit order in bytes
cout << ((c >> i) & 1);
}

i have binary file as input and i need to read it simple by bits. If i wanted to read file by characters i would use this:
ifstream f(inFile, ios::binary | ios::in); char c; while (f.get(c)) { cout << c; }
Output of this code is sequence of characters, what i need is sequence of 1 and 0. Function get() return next character and i could not find any ifstream function that would return next bit.
Is there any similar way how to achieve it ?
Thank anyone for help.
