Unsigned Short to Char[X]

I need to take a value out of an unsigned short and add it to a char array.

ex.:

unsigned short a = 6849;
char b[20];

any idea about how to place "6849" into b ?

Thank you !

your task doesn't really make sense. do you have a more complete explanation of what you are required to do?

xxxxxxxxxan unsigned short is 2 bytes. you can do shifts and masks to get the LSB and MSB and put them in b[0] and b[1] if thats what you want.

never mind. you probably want to turn 6849 into a printable string?

one way is

Code:

---

count = snprintf(b,sizeof(b),"%u",a);

---

I'm totally lost :)

I'm sending a char[] through a socket and I want to send some numeric information.

I guess you mean using those operators >> << ...

I will go read about this !

Thank you

i was thinking too much. if you want to use iostreams, then using << is the way to go. but do you want to send it as binary data or as ascii string?

Hummmm

I don't know much about hidden functionnality behing sockets but I already send some text ("ABCDE") through a char and i can get it back on the other side ("ABCDE") .

i guess it's called ascii string ? :)

is count supposed to be a char[] ?

I suggest you use stringstreams to convert data to a string before sending it:

Code:

---

std::stringstream stream;
stream << my_integer;
std::string mydata = stream.str();

---

Now you can send the raw string by using the c_str() member function to get the string and size() to get the length.

To extract the data on the other end, you can do:

Code:

---

std::stringstream stream(received_data);
stream >> my_data;
