Bit operations on buffers

[PSN]

Hello Group,
I have a character array of size 2;

char *pArray=(char *)malloc(10);
memset(pArray, 1, 10); // 0000000100000001

I want to apply shift operations, so as '&' and '|' operations on the
whole buffer at once. How can i do it ??

Ex: pArray & 0x01 ----> 1;
pArray >> 1 ----> 0000000010000000;

The 2 character buffer is just an example, and i wish to use buffers
of variable sizes.

Thanks a lot again for your time,

Prakash

Why are you using malloc?

memset(pArray, 1, 10); // 0000000100000001

Have a look at std::bitset.

I am aware of the bitset container.

Can i dare to say, i want to reinvent the wheel and wish to know
exactly what i am doing behind the covers !!

thanks for your time again,

In that case, rolling your own should prove an interesting exercise!
