Sum of Series||C language||programming_info ||Series problem 7

Calculate sum of series:

1+1/2+1/3+1/4+.....N

Solution using C language:

#include<stdio.h>

int main()

{

  int i, N;

  float sum=0;

  printf("Enter N:");

  scanf("%d", &N);

  if(N<1){

    printf("Enter value of N > 0.");

    exit(1);

  }

  for(i=1; i<=N; i++)

  {

   if(i==1)

   {

     sum=1;

     printf("Series = 1");

   }

   else

   {

     sum = sum + (float)1/i;

     printf(" + 1/%d", i);

   }

  }

  printf("\nSum of the series = %0.2f", sum);

  return 0; 

}

Output:

Enter N:5

Series = 1 + 1/2 + 1/3 + 1/4 + 1/5

Sum of the series = 2.28
