Definition of harmonic progression (A.P.):

This C Program calculates the the sum of H.P series. This program is used to find the sum of the harmonic progression series. Here H.P stands for harmonic progression. Harmonic progression is a progression formed by taking the reciprocals of an arithmetic progression.

Example of H.P. series:

1/3, 1/6, 1/9, …
If you take the reciprocal of each term from the above HP, the sequence will become
3, 6, 9, ...
which is an AP with a common difference of 3.

C Program

#include<stdio.h>
#include<conio.h>
void main() {
	int n;
	float i, sum, t;
	printf("1+1/2+1/3+......+1/n\n");
	printf("Enter the value of n\n");
	scanf("%d",&
	amp;
	n);
	sum=0;
	for (i=1;i<=n;i++) {
		t=1/i;
		sum=sum+t;
	}
	printf("%f",sum);
	getch();
}

Output:

1 + 1 / 2 + 1 / 3 +......+1 / n
Enter the value of n
