Question

please answer☹️☹️☹️☹️.. this a C++ programing question from sumita arrora.

Answer 1

#include <iostream>

#include <math.h>

using namespace std;

int main()

{

   float x, sum, term, fct, y, j, m;

   int i, n;

   y = 2;

   cout << "\n\n Find the sum of the series 1 - X^2/2! + X^4/4!-....:\n";

   cout << "---------------------------------------------------------\n";

   cout << " Input the value of X: ";

   cin >> x;

   cout << " Input the value for nth term: ";

   cin >> n;

   sum = 1;

   term = 1;

   cout << " term 1 value is: " << term << endl;

   for (i = 1; i < n; i++)  

{

       fct = 1;

       for (j = 1; j <= y; j++)  

 {

           fct = fct * j;

       }

       term = term * (-1);

       m = pow(x, y) / fct;

       m = m * term;

       cout << " term " << i + 1 << " value is: " << m << endl;

       sum = sum + m;

       y += 2;

   }

   cout << " The sum of the above series is: " << sum << endl;

}
