Hexa Decimal Addition in C

[sarchanakumar]

Hi friends, I want to write a program to add two hexa-decimal numbers. I know there is no way of direction addtion. My logic is, first convert two hexa-numbers into decimal after that we add and finally we have to convert the resultant decimal into hexadecimal. Is it right? Give your suggestion.

I may be wrong, but I know hexadecimal numbers can be decalred 0x0f45 (for example, and stored as integers so I would imagine you can add them and do all sorts of things. I'm pretty sure when you are using printf to print to the screen, you can manipulate %d to display hexadecimal values

information is stored within the computer in binary and converted into decimal, octal or hex notation when we input and output numeric data. e.g. in to print a value in hex

    int i=0x02F4B;
    printf("i in hex %#0x\n", i);
 

and in C++

    int i=0x02F4B;
    cout << "i in hex " << setiosflags(ios::showbase) << hex << i  << endl;
 

when run both give
i in hex 0x2f4b

similar conversion is used to input data in hex
