the code that i have coded is of operator overloading for incrementing and the i need some help in the operator overloading for decrementing ,mutiplication and division please send the following in a code form shall be thankful..

What's the question? You need to ask a specific question and point us to some difficulty you are having. Sounds like you want someone to turn the code below into decrementing , multiplication and division operators and send you the finished product or something?

void operator ++()
	  {
	   kg++;
	   grms+=10;
	  }
	  void operator ++(int)
	  {
		kg++;
		grms+=10;
	  }

Your operators ++ are looking strange. As an example here the operators ++ for int:

// prefix increment
 int operator ++ (int i)
 {
        i = i + 1;
        return i;
 }

 // postfix increment
 int operator ++ (int i, int)
 {
        int temp = i;
        i = i + 1;
        return temp;
 }
