After converting the hexstr to Hex and storing the Hex in a char*
Hi All,
My main intension of is to convert the Hexstring stored in a char* into hex and then prefixing it with "0x" and suffix it with ','
This has to be done for all the hexstring char* is NULL.
Store the result prefixed with "0x" and suffixed with ',' in another char* and pass it to another module.
I just want to print and see the values in the result char* to see if it is stored as 0x30, (say when the input char* a = "30" )
How can I verify the values stored in the char*...?
I cannot print it neither as %s nor %x both gives junk values.. %s gives junk because it is hex and %x gives junk because i have formatted with "0x30," i think.. But am not clear and don't know how to check if the values got stored in this format. 0x30,
Hi everyone!
I was wondering if anyone knows how to change hex code back into ascii.
when i process a form:
" / " turn to " %2F "
" @ " turns to " %40 "
" ' " turns to " %27 "
" ( " turns to " %28 "
" ) " turns to " %29 "
this is my code so far: order.txt
thanks,
primal

Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
