printing hexadecimal value in c++

[Pratapd]

Hello,

I'm trying to print the hexadecimal value for a string.
Actually, it was already encoded by my application into utf-8. And I would like to check the converted hex-code.
Could some one please let me know how to print it to a file ?

pFile = fopen ("C:\\myfile.txt","w");
fprintf (pFile, "%X ",c);
The above code didn't work!!

Thanks a lot for your inputs,
Pratap

You haven't said what type c is but I am assuming an array of char

char c[100];

You are printing out the hexidecimal representation of the address of the memory that stores the array.

To print the value of the character you need to pass the character to fprintf not the pointer to the array

fprintf (pFile, "%X ",c[0]);

Obviously you will need to repeat for all used entries in the array.
