File i/o Question

I am grabbing a time slot from a text file

---text file--

11:01 am.

When I want to grab the minutes column, it only grabs the '1' instead of the '01'. I have the variable set to int. Any suggestions?

Why do you need the tens place? Why not use a Date class, then you can just use some sort of Date.getMinutes () function?

Can you add it yourself? This is a QAD, but very dirty (using a getMinutes() function or something close would be a much, much better idea, lest you end up on The Daily WTF) .

[code=cpp]
if (i_min < 10 && i_min >= 0)
cout << '0' << i_min;
[/code]

Well, its something I havent learned yet, but why won't the program take 01? And is there any other way besides the if statement to add that on?

I'm guessing you're taking it as an int, right? Well, numbers are stored in binary, so what the computer sees is:

0000 0001

It can't tell the difference between 01 and 1, so it prints 1. However, if you use a date class, I'm guessing that they will come as objects, and print out as '01' or '0x'.
