Answer 1

Answer:

int sumeven(int lis[],int n)

{

   int sum_e=0;//integer variable to store the sum.

   for(int i=0;i<n;i++)

       {

           if(lis[i]%2 == 0)//if the number is even adding to sum_e.

           sum_e=sum_e+i;

       }

   return sum_e;//retuning the sum.

   

}

Explanation:

The above written function is in C++.This function find the sum of even numbers in the list provided.It loops over the array and if the number is even adds to the variable sum_e finally return sum_e which having the sum of even numbers now.
