Thread: Sprintf masks Doubt(s)

i have tried with this:

Code:

    sprintf(msg, "Teste %02.2d",100);
    sprintf(msg, "Teste %02.2d",100000);
    sprintf(msg, "Teste %02.2d",100000000);


    sprintf(msg, "Teste %2.2d",100);
    sprintf(msg, "Teste %2.2d",100000);
    sprintf(msg, "Teste %2.2d",100000000);

And still the same result for both.

1 - And again, i dont want you to write a program for me, i just want to know whats the difference between 2 masks(o2.2 and 2.2).

2 - I looked at the reference before and i understood that the 0 is used for left padding... Buf even if i dont use the 0 i still got the padding of 0 on the .2 number...

i just want to know something like "ITS FOR PADDING" or "ITS FOR THIS OR THAT", dont a program write if you dont want to your "majesty" ^^

Ummm... why don't you try changing all those 2s to 8s and see what happens?

Really... rather than getting all ........ed off, do some real experimenting.

i still got the same results, with or without the '0' preceding the width... Just for information, i'm using VS2010 express

thank you

Why it doesn't matter in VS 2010? in GCC/GPP i have to put the 0?

Because that's the way the libraries are written.

Really... I'm no more telepathic than you are... I have no idea why programmer A decides one thing and programmer B decides another.
Just accept these things as they are, use them, and get on with it.

man, you really S U CK S... telepatic? Its not about to accept and use! Its about WHY IS DIFFERENT or IS REALLY DIFERENT? What a stupid reply... leave this for who want to discuss. You should be banished for answer questions like this.

and don't reply this, put your idead in you A SS
