Proper format for displaying time

[dragonbane]

I'm coding a program to add and subtract time from a user given time. The problem I've run into is that I have the hours and minutes in int form. I need to display the minutes as 00.. 09. If I enter them as 00 they still come out as 0. How do you format you integer output to have two significant figures?

For output, you need to #include <iomanip> and use some of the proper manipulators.

For input, the istream doesn't care how many zeros you have in front of a number, so long as you set it to read decimal (or whatever) numbers.

Hope this helps.

Hi. This sounds interesting but you haven't provided much information. Maybe you should include some of the code and point out exactly what you're trying to do. I think maybe you want the hours to be integers and the minutes to include a decimal. That's why I'm interested. Not to say it's not worth responding just to try to help. So try to add more info, please.

Well, I don't need decimals, I just need the numbers 1-9 to display zeros before them so that the time would be 5:03 instead of 5:3.

There's more to my code (error checks and such) but a simplified version is:

cout<<"Enter the current Hour: ";
cin >> hour;
cout << "Enter the current Minutes: ";
cin >> minute;
cout << "Initial time is: " << hour << ":" << minute << endl;

All I need to know is how to set the output to display two figures all the time.

From Duoas post I though maybe I could use something like:

if (minute < 10 && min > 0)
{
cout << setfill ('0') << setw (1);
cout << minute;
}

Do I have other options or is that going to be the simplest one?

[mucygni]

One simple solution could be:

if(minute >= 0 && minute < 10)
cout << '0' << minute;
else
cout << minute;

I did it for a school assignment recently. I don't know much, but I'm pretty confident saying that you shouldn't make things more complicated then they need to be. That's all.

@dragonbane You are doing it right. You just need to setw(2) rather than 1

std::cout << std::setfill('0') << std::setw(2)
