Answer 1

// C program to find sum of series  

#include <stdio.h>  

 

// Function to return sum of 1/1 + 1/2 + 1/3 + ..+ 1/n  

double sum(int n)  

{  

 double i, s = 0.0;  

 for (i = 1; i <= n; i++)  

     s = s + 1/i;  

 return s;  

}  

 

int main()  

{  

   int n = 5;  

   printf("Sum is %f", sum(n));  

   return 0;
