Write a C program to determine the sum of the following harmonic series for a given value of N.

1/1² + 2/2² + 3/3² + ………..  + n/n².

Problem name:  Write a C program to determine the sum of the following harmonic series for a given value of N.

1/1² + 2/2² + 3/3² + ………..  + n/n².

Algorithm:

Step 1: Start

Step 2: Input the value of N

Step 3: Initialized i=1

Step 4: While i<=n repeat step 5

Step 5: sum=sum+(i+i/i), i++

Step 6: Print the sum is

Step 7: End

C Program:

#include<stdio.h>

int main()

{

    int n,i;

    float t,sum=0.0;

    printf ( “ Input an Integer Number : “);

    scanf("%d",&n);

    for (i=1;i<=n;i++)

    {

        t=i*i;

        sum=i+(i/t);

    }

    printf("%f",sum);

return 0;

}
