C Program To Print Sum of Series 1+1/2+1/3+1/4+…+1/n

Here, we have listed How To Print The Sum of Series of Numbers in the format 1 + 1/2 + 1/3 + … +1/n in C Programming Language. It is important that we should know about the How A For Loop Works before getting further with the C Program Code.

We have listed following Methods To Find The Sum of Sequence in C Programming:

  • Addition of Series without Function
  • Sum of Sequence with Function

In this C Program, we take a Limit as an Input from the user. Suppose, if the user enters the Limit as 5, the program will calculate the Sum of Sequence starting from Numbers 1 to 5.

Example

1 + 1/2 + 1/3 + 1/4 + 1/5 = 2.283333

Method 1: Find Sum of Sequence without Function in C

#include<stdio.h>

int main()
{
    
    double count, limit, sum = 0;
    printf("nThe Sum of Series 1+1/2+1/3+...+1/n n");
    printf("Enter The Limit:t");
    scanf("%lf", &limit);
    for(count = 1;count <= limit;count++)
    {
        sum = sum + (1/count);
    }
    printf("nSum of Series:t %lf", sum);
    printf("n");
    return 0;
}

Method 2: Calculate Sum of Series using Function in C Programming

#include<stdio.h>
 
double calc_sum(double x);
 
int main()
{
    double limit, res;
    printf("nThe Sum of Series 1+1/2+1/3+...+1/n n");
    printf("Enter The Limit:t");
    scanf("%lf", &limit);
    res = calc_sum(limit);
    printf("nSum of Series:t %lf", res);
    printf("n");
    return 0;
}
 
double calc_sum(double x)
{
    double count, sum = 0;
    for(count = 1;count <= x;count++)
    {
        sum = sum + (1/count);
    }
    return sum;
}

Output
