Question

I need to get each Character of a string as a sequence of bits either in an array or just traverse over it in a loop, either way works. This is something I used to do in ASM way back, and am not sure how that can be done in c++.

EDIT: I am trying to replicate what I did sometime back with asm, reading a file in memory and traversing it bit by bit, manipulate each bit, do some more cyphering and save it back.

Basically a simple Encryption. Its not a homework neither it is a project.

You can iterate through it using bit operators:

unsigned char c = 'a'
for(int i = 0; i < 8; i++)
{
  std::cout << (c >> i) & 1 << std::endl;
}

This will shift c to the right for i position, and use bitwise AND to get value of the least significant bit.
