Write a program in C++ to find the sum of the series 1 + 1/2^2 + 1/3^3 + ..+ 1/n^n
Sample Output:
Find the sum of the series 1 + 1/2^2 + 1/3^3 +.....+ 1/n^n: ---------------------------------------------------------------- Input the value for nth term: 5 1/1^1 = 1 1/2^2 = 0.25 1/3^3 = 0.037037 1/4^4 = 0.00390625 1/5^5 = 0.00032 The sum of the above series is: 1.29126
الأجوبة
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
double sum = 0, a;
int n, i;
cout << "\n\n Find the sum of the series 1 + 1/2^2 + 1/3^3 +.....+ 1/n^n:\n";
cout << "----------------------------------------------------------------\n";
cout << " Input the value for nth term: ";
cin >> n;
for (i = 1; i <= n; ++i)
{
a = 1 / pow(i, i);
cout << "1/" << i << "^" << i << " = " << a << endl;
sum += a;
}
cout << " The sum of the above series is: " << sum << endl;
