Write an iterative function $\texttt{float harm_it(int n)}$ which computes the sum of the first n terms of the harmonic series (n is passed in parameter): \(1 + \frac{1}{2} + \frac{1}{3} + \cdots + \frac{1}{n}\)

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

float harm_it(int n) 
{
	float res=0.0;
	int i;
	for (i=1; i<=n; i++) 
		res=res+1.0/i;
	return res;
}

void main()
{
	int n;
	do{
		printf("Enter n: ");
		scanf("%d",&n);
	}while(n<=0);

	printf("Value = %f\n", harm_it(n));
	getch();
}
