Dec ----to----> Hex <<urgent>>

hey guyz!!!

doez anybody know how to change the value of a variable to Hexadecimal from decimal???
in VC++.......

thanks a lot!!!!
i need it urgently,,,,,,,,,,
pls ,,,,,,,
HELP!!!!

Of an integer? Integers are represented as binary in memory, it only depends on you formatting how it is outputted:

printf("%x", i);
or
cout << setbase(16) << i;

thanks,,,,,, cornedbee,,
:D

hey thanks a lot cornedbee =-
but how to pack with 0's(zeros) in front???

=o)

hey nvm,,,
i tried "%04x",, it works.....
anyway thanksss,,,,,,

Use the first function, the 2 last functions will be use by the first one.

Code:

---

//Use this one
string AsciiToHex(const string &sAll)
{
        string sHex;
        string sTempo;
        char cEach;

        for (int i = 0 ; i < sAll.length() ; i++)
        {
                cEach = sAll.at(i);
                sTempo = DecToHex((int)cEach);
                sHex.append(sTempo);
                sHex.append(" ");
        }//End For

        return sHex;
}//End AsciiToHex
//Do not use this one
string DecToHex(const int &iDecimal)
{
        int i1;
        char c[1];
        char c2[1];
        string sHexa;

        i1 = abs(iDecimal / 16);
        itoa(i1,c,10);
        i1 = abs(iDecimal%16);
        itoa(i1,c2,10);
        if (i1>9)
                c2[0] = ConvertH(i1);

        sHexa.append(c);
        sHexa.append(c2);
        return (sHexa.substr(0,2));
}//End DecToHex

//Not this one either
char ConvertH(const int &iNumber)
{
        switch(iNumber)
        {
        case 10:return 'A';break;
        case 11:return 'B';break;
        case 12:return 'C';break;
        case 13:return 'D';break;
        case 14:return 'E';break;
        case 15:return 'F';break;
        default:return 'X';break;
        }//End switch
        return 'X';
}//End ConvertH
