Help with program harmonic series

I have tried to code the following harmonic series as below but the progrma outputs 1.000000 only, could someone point out where the flaw is ?

1+1/2+1/3+...........+1/n

Code:

---


#include<stdio.h>
#include<conio.h>
void main()
{
int n,deno;
printf("enter the value of n");
scanf("%d",&n);
deno=1;
float sum = 0;
while(deno<=n)
{
sum=sum+(1/deno);
deno++
)
printf("%f",sum);
getch()
}

---

When deno is an int, 1/deno uses integer math and the result for any nonzero deno will be zero. Try 1.0/deno.

But 'sum' I thought is of type float and the whole expression is
real expression and hence the right hand side of the assignment operator sum=sum+(1/deno) should be of type float ,isnt it ?

No. Reread my reply.
