I understand... so 0 is used to specify the pad when you put just the width, right? like "%03d". When you use width.precision, the precision of the integer will be always padded with 0s...

So,...

I said that i tried it, and get answers like yours is over the top...

1 - I read the documentation before i post this question and i read it again when you said to. specifically on the width it says:



widthdescription

(number)
Minimum number of characters to...

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...

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

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

thank you

i have tried with this:




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

Like what? i tried others too but with or without 0 (2.2 / 02.2) i got the same result. this is not a homework or something that i want you to do for me... If i'm asking here is because i really want...

Hi!

i dont know what is the difference between the 2 masks (the result
on visual c++ 2010 is the same):




sprintf(msg, "Number %2.2d",10);
sprintf(msg, "Number %02.2d",10);

Thx for suggestions laserlight, i just have one more question...

if i make a constructor in the struct, it will affect the result of sizeof(struct)???

thank you!

i forgot to say that the stInfo will be inserted into a vector of stInfo's... So it have to be a stInfo. And when i say tags i mean ID's like "001" or "002". It will be easier to do if a just cast...

I see... The idea was cast and then evalue in the struct fields, using they sizes and etc... Its really not safe to do this?

i will use the first field to identify a tag and then according to the tag process the other fields. Its just a way to separate things to process.

Hi there,

So i have a struct:



struct stinfo{

char info1[19];
char info2[5];
