Sum of Series using C :1 + (1 / 2) + (1 / 3) + ...+ (1 / n)

Source Code:

1. //C program to calculate sum of series.
2. //1 + (1 / 2) +  (1 / 3) + ...+ (1 / n) 
3. #include<stdio.h>
4. #include<conio.h>
5. int main(){ //Variable Declaration.
6.     float number, sum = 0, i;
7.   //Take input from User.
8.     printf("\n Enter the number: ");
9.     scanf("%f", &number);
10. //Count upto n number using loop.
11.     for (i = 1; i <= number; i++)
12.     {
13.         sum = sum + (1 / i);
14.         if (i == 1)
15.             printf("\n 1 +");
16.         else if (i == number)
17.             printf(" (1 / %f)", i);
18.         else
19.             printf(" (1 / %f) + ", i);
20.     }
21.     printf("\n The sum of the given series is %f", sum); //print the output.
22. }

Output:

 Enter the number: 5

 1 + (1 / 2.000000) +  (1 / 3.000000) +  (1 / 4.000000) +  (1 / 5.000000)

 The sum of the given series is 2.283334
