Hi group,
how to convert a string to a vector of unsigned char ?
I used to iterate trough the string to set the vector, but I think
this is not the best way to do this.
I'm a beginner with the STL
How about allocating the vector ? should I know before the size ?
And I would like to do then opposite conversion, from an unsigned char
vector to a string.
How to do this ? how about special caracters ? (\n for example)
Thanks for your help
Best regards,
N.

std::string s = "abra kadabra";
std::vector<uns igned charv( s.begin(), s.end() );

Huh.

vector to a string.

std::string t( v.begin(), v.end() );
how about special caracters ? (\n for example)
Irrelevant.

If you have very large strings you can run v.reserve(s.siz e()) before
inserting, which might give a speed improvement. But you don't have
to.

I want to read from a file into a vector<unsigned char>. Right now my
code looks like this:

enum { SIZE = 100 };
vector<unsigned char> buf(SIZE);
fread(&buf, 1, SIZE, f);

Hi.
I'm in the process of making a GUI for a function someone else wrote,
and i've come across a type i'm unfamiliar with, namely
"std::vector<unsigned char>". I need to get the contents of this
variable into a form I can display in a text box, but i'm not sure what
to expect inside of the variable, whether I can just treat it like an
array e.t.c. Any help would be appreciated.
Thanks,

Hi.
Thanks to everyone who replied to my last post, it turns out it wasn't
the line where I was trying to treat the variable in question as an
array which was the problem, but the line above.
char temp;
std::vector<unsigned charmmessage;
while (!done){

what's the best way to convert a list of string to a vector<int>?
what i have now is for loop and iterate each char in the string
string base="";
//i have vector<int>row,vector < vector<int>row > mat;
//what i want to do with the string is that everytime char != ";"
row.pushback(str that convert to int)

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
