I am implementing turbo encoder, I will give some data as a input and i am converting it into the binary, since i don't know how to store and which data type for binary values, i have stored those binary values as integers only. Now i need to concatenate three bits at a time, I need only 1's and 0's not the integer values. If i shift these values i will get more than 1.

Of course.
Now look at decimal case:
if you 'concatenate' the digits 1,5,7 then you get the number 157 that is no more in the 0-9 range.
An alternative would be using strings, that is, you concatenate the character representations of the digits into a string ('1'', '5', '7' => "157").
You may apply exactly the same argument to binary (that is base 2) digits: if you concatenate 1,0,0 you get the number 101, that is decimal 5, no more in the 0-1 range. The string concatenation method would give you "101".
You may find interesting the std::bitset[^] class.
However it does not prevent you from gaining a proper understanding of numerical bases (see, for instance, Numeral System at Wikipedia[^]) and how numbers are stored in computers.

This has nothing to do with C/C++, it's how computers work. If you will not use the shift operators to store the three bits together then you cannot store them.

Which the compiler will almost certainly optimise into shift operations.

possibly. but that extends the definition of "you" quite a bit.
int Answer = u + u + u + u + p + p + q;

you originally wrote "If you will not use the shift operators to store the three bits together then you cannot store them."
that's the "you".
i think it's reasonable to differentiate between what the programmer writes and what the compiler does.

Sorry, but I don't understand what point you are trying to make.

though richard solutions is best.. i am suggesting simpler approach for this in my college days 
int result = i*100 + j *10 + k;
Jokes apart! are you looking for it's integer equivalent. i.e. say you have bits like this i=1,j=0,k=0 for which decimal equivalent is 4 ( binary of 100 = 4 i.e. 22 + 0 + 0 )

No i dont need the decimal value of binary. I need to that as it is as 1's and 0's.
if i have u=1; p=0; q=1;
Then i need result = {u,p,q} = "101" (its neither decimal '5' nor decimal 'one hundred one')
Just i need to concatenate bits.
or else help me how to store binary values and which is the data type for that.

if you looking for string value as i understand by double quote used by you, you can use sprintf or sprintf_s.
now if you want to store the binary value resulting from you operation (as you mentioned they are only 3 bit coming), you can use char datatype (1 byte) and store the decimal equivalent of it there, internally it store its binary equivalent only,
for say you got 101 which decimal equivalent is 5 and when you store same in char variable, it binary representation would be
00000100

But i need to concatenate the bits which are in different variables. how to concatenate those.. Since i cannot use shift operator here because of binary.

What on earth are you talking about? I have shown you exactly how to concatenate these fields into a three bit value. If you really cannot understand that simple operation then I don't think you are going to get very far with this project.

Can you please suggest me a program to convert a string into binary, that store in char data type.
|
|
|
|
|
char * p = "101";
char * pEnd;
int val = strtol(p, &pEnd, 2);
char charval = (char)val;
this may fail if p is more than 7 bits long (since that could overflow a signed char).

I want some help developing a program in C++ that creates course scheduling. Want a start and a good thinking.

No...m not here hiring a coder to do this work for me...just want a expert guidance.. thats it

Ok, so show us what you've got so far and we'll guide you. Read #2 here.
For starters, what is course scheduling? I can come up with at least a dozen descriptions for that and may not even get close to what you are after. Is this a console application, or does it have a GUI? Will it be reading from a file? What does the output look like?

I think you misunderstand what's on offer here. We can answer specific questions but what you are asking for is far too broad for these forums. You need to go and do some research for yourself and come back here when you have a specific technical question.

what it your initial analysis about project, like IDE, your initial thinking etc?

Start with the requirements. List them.
Next step: Design the GUI and describe Use Cases, i.e. the different ways you want to allow a user to use your system, and the inputs and outputs.
Then if you need some guidance in implementing the GUI or the processing algorithms, someone here may help you.
