C Program to display the sum of harmonic series 1+1/2+1/3+...+1/n

In this tutorial, we are going to write a C Program to display the sum of harmonic series 1+1/2+1/3+...+1/n in C Programming with practical program code and step-by-step full complete explanation.

C Program to display the sum of harmonic series.

 
#include<stdio.h>
#include<conio.h>

void main()
{
	int n,i,sum=0;

	clrscr();

	printf("Enter any number: ");
	scanf("%d",&n);
	printf("1 +");

	for(i=2;i<=n-1;i++)
	{
		printf(" 1/%d +",i);
	}
	for(i=1;i<=n;i++)
	{
		sum=sum+i;
	}
	printf(" 1/%d",n);
	printf("\nSum=1/%d",sum+1/n);
	getch();
}

Output

 
Enter any number: 7
1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7
Sum = 1/28
