Basics: Is it possible to print 05 rather than 5?

[MRehanQadri]

int x;
cin >> x;
//If user writes 05 in x. Then I want that 05 should be printed when we cout << x;
//If user writes 005 when prompted for x then printing x should print 005, because 005 may be a telephone extension.
Is there any way?

Take the input in as a string.

#include <string> // to use the string class
#include <iostream>

using namespace std;

int main()
{
    string input;
    cout << "Enter number: ";
    getline(cin, input);
    cout << "You entered: " << input << endl;
    cin.get();  // pause program
    return 0;
}

if your using a telephone #, it sounds like you should be using a string instead of an int for this situation.

std::string strExt;

std::cin >> strExt << std::endl;

[MRehanQadri]

Well, thanks but is there any other alternative?

[AnathemA_]

as far as i know no. Why do you want the extension as an integer?

[MRehanQadri]

Because it's required in the Assignment.

Because it's required in the Assignment.

Then I suspect you've misinterpreted the assignment. Could you post it?

[AnathemA_]

    int x;

    cin >> x;
    cout << setw(3) << setfill('0') << x;



This might work for you.

That's what i'm thinking. The professor is probably meaning the Area code should be integers only, yet storage to be used will be a string :P

But then again, maybe not. You don't know beforehand how many leading 0s there are. And there is no way to find out unless it's a string.
