1) The program reads an integer, that must be changed to read a floating point. 2) You will need to move that number into a floating point register and then that number must be copied into an integer register. 3) You will need to extract the exponent from the integer register and stored in another register. 4) You will need to insert the Implied b

1. Get the number

2. Declare a variable to store the sum and set it to 0

3. Repeat the next two steps till the number is not 0

4. Get the rightmost digit of the number with help of remainder ‘%’ operator by dividing it with 10 and add it to sum.

5. Divide the number by 10 with help of ‘/’ operator

6. Print or return the sum

# include<iostream>

using namespace std;

/* Function to get sum of digits */

class gfg

{

   public:

   int getSum(float n)

   {

   float sum = 0 ;

   while (n != 0)

   {

    sum = sum + n % 10;

    n = n/10;

   }

return sum;

}

};

//driver code

int main()

{

gfg g;

float n = 687;  

cout<< g.getSum(n);

return 0;

}

Explanation:

the answer is c
