Answer 1

Here is the solution to above formula in C++. PLEASE GIVE A THUMBS UP!!

Read the code comments for more information

$y = \sum_{k=0}^{9}n$

C++ Code

#include<iostream>
using namespace std;

//function receives the integer argument n
//it returns the answer of summation
double function(double n)
{
   //variable used to sum the values
   int sum=0;
   //run a loop which is equivalent to Summation in mathematics
   //from k=0 till k<=9
   for(int k=0;k<=9;++k)
   {
       //add value of n in sum
       sum+=n;
   }
   //return the final answer
   return sum;
}

int main()
{
   //create a variable n to take user input of N
   double n;
   //print message and take user input
   cout<<"ENTER THE VALUE OF N: ";
   cin>>n;
   //display the calculated summation value
   cout<<"VALUE OF Y IS: "<<function(n)<<endl;
   return 0;
}
