storing data in hexadecimal format

[aj2903]

hii....
i want to store data into file in hexadecimal format.

How can it be done ?

Follwing is the code I tried :

QFile fileC("test_1.hex");
    QTextStream outC(&fileC);
 
 
 unsigned char cData = 47;
outC << cData;l

QFile fileC("test_1.hex");
    QTextStream outC(&fileC);


 unsigned char cData = 47;
outC << cData;l

To copy to clipboard, switch view to plain text mode 

The code writes 47,but in Char Format.How can we conver it into hexadecimal
