Question

Write an algorithm that determines whether the sum of the digits of N, a three-digit number, is odd or even.
So like if N was 324, it would see if the result of 3+2+4 was odd or even

Answer 1

Explanation:

Input : n = 687

Output : 21

Input : n = 12

Output : 3

// C program to compute sum of digits in

// number.

# include<iostream>

using namespace std;

/* Function to get sum of digits */

class gfg

{

public:

int getSum(int n)

{

int sum = 0;

while (n != 0)

{

sum = sum + n % 10;

n = n/10;

}

return sum;

}

};

//driver code

int main()

{

gfg g;

int n = 687;

cout<< g.getSum(n);

return 0;

}
