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;

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

//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
