How to convert bytes to string in C programming

[parvathireddy]

could anyone explain me how to convert bytes of data to string using c programming , would be very thankful. I searched but i didnt get appropriate one .


Example : 112131(bytes) to string ("some sample")

If by bytes you mean a series of ASCII digits then you put/copy the digits into an array of char and add a zero terminator to the end of it

char bytes[] = {'1', '1', '2', '1', '3', '1'};
char string[11];
 
memcpy(string, bytes, sizeof bytes);
string[sizeof bytes] = '\0';
 

If you mean binary data you can use sprintf

int bytes = 112131;
char string[11];
 
sprintf(string, "%d", bytes);

Thank you, Banfa .

But we tried with that one and its nt working here. is there any alternative apart from this. I am using visual studio 2010 IDE

Which one?

Also there is not reason that either of those should fail to work on any platform since they are both portable.

This would be easier if you posted a snippet of your code showing what you are attempting.

@parvathireddy: please clarify your example.

Are you saying that you want a program that would convert the three bytes 0x11, 0x21, and 0x31 into the 11-character (plus null) string "some sample"?
