Please help I am having a nightmare with this.

I need to convert a decimal number in to Hex and binary. Dec_Num is a random integer number up to 255. Then I have Bin_Num (integer) and Hex_Num (Char - as letters are needed).

I have the following.

Bin_Num =Convert_to_Dec(Dec_Num)
Hex_Num =Convert_to_Hex(Dec_Num)

Functions :

int Convert_to_Dec (int a)
{

Return(Result);
}

int (Convert_to_Hex (char a)
{

Resturn(Result);
}

Now heres my problem I have tried so many ways and cant get anyting to work. To work out binary you simply divide by 2 and store the remainder, so I set up an array to store remainder. But my returned result NEEDS to be a integer, so I converted to an integer, but the result is still always wrong.

Also Hex basiaclly the same, but obviously need to return a char result as it will contain letters. NOTE : I AM NOT ALLOWED TO USE ANY EXSISTING C++ COMMANDS TO WORK OUT THE DEC AND HEX, I MUST WRITE MY OWN FUNCTION TO DO IT. PLEASE SOMEONE HELP !!

PLUS : The returned results must be integer and char (basiaccly anything apart from ARRAY!)
