Question

Write a menu driven program to print the sum of the following series-[10]i)S=1 + (1/3) + (1/5) + ...... + (1/19)ii)S = a2+ a2/ 2 + a2/ 3 + ...... + a2/ 10

Answer 1

Answer:

// C++ program to find the sum of

// the given series

#include <stdio.h>

#include <math.h>

#include <iostream>

using namespace std;

// Function to return the

// sum of the series

float getSum(int a, int n)

{

// variable to store the answer

float sum = 0;

for (int i = 1; i <= n; ++i)

{

// Math.pow(x, y) returns x^y

sum += (i / pow(a, i));

}

return sum;

}

// Driver code

int main()

{

int a = 3, n = 3;

// Print the sum of the series

cout << (getSum(a, n));

return 0;

}
