get the input but still the input should remain

[Prakhar]

Hello,
I know the subject line gives a little idea about the problem.

Well, I want to get the input ,and after taking the input, I AGAIN
want to get the same input.

For Eg.,

Suppose input is 23:
../a.out 23

Now, I want to get 23, then store it in a variable and then again want
to get the same input, i.e., 23.

string strInput;
cin>> strInput;

int intInput;
cin>> intInput;

Both of them should be 23, ie, I should be able to get the input even
if I have already taken this input.

Thanks.-Prakhar

Use a stringstream:

std::string strInput;
std::cin >> strInput;

std::stringstream ss;
ss << strInput;

int intInput;
ss >> intInput;

That's not how things are done in C++, usually. What you [usually]
should do is store your input, like you propose, in a string, and when
you figure out what to convert it to, use, for example, istringstream
to "read it again" from that string.

What do you mean by "input"? What you show is a command-line value. Is
that what you are talking about? Or a value entered after the program
starts running?
