I need to convert a Decimal number to HEX (not allowed to use pre-written commands or functions). I have passed the integer decimal in to a function (a) and now need to convert to HEX equivelent. Any1 know of a good method, this is what i tried but cant get it to work. (Need to return a char value!!)

//Function to convert DEC to HEX
int Process_Dec_To_Hex(int a)
{
char Result=0;
char Remainders[7]={0};
int Temp_Remainder=0;

for(int x=6;x>0;x--)
{
Temp_Remainder=a%16;
Remainders[x]=Temp_Remainder;

if(Temp_Remainder==10)
{
Remainders[x]='A';
}
if(Temp_Remainder==11)
{
Remainders[x]='B';
}
if(Temp_Remainder==12)
{
Remainders[x]='C';
}
if(Temp_Remainder==13)
{
Remainders[x]='D';
}
if(Temp_Remainder==14)
{
Remainders[x]='E';
}
if(Temp_Remainder==15)
{
Remainders[x]='F';
}
a=a/2;
}

// To convery the array to a char
for(x=0;x<6;x++)
{
char cBits[7];

for(int i = 0; i<6; i++)
{
cBits[i] = Remainders[i]+0x30;
}
Result=atoi(cBits);
}
return(Result);
}
