trying to get harmonic progression sum in c...........help me....

Question

here's my code....

#include <stdio.h>
#include <stdlib.h>

int main()
{
int x, n;
x = 1;
double y;
y = 0.0;

printf("Enter a number:\n");
scanf("%d", &n);
while(x<=n)
{
y = y + 1/x;

x = x + 1;

}

printf("%.1f", y);

return 0;
}

tell me...what did i do wrong

Answer 1

`x` is an int, and so is `1`, so `1/x` does integer division! The result will be rounded down to the next int, which is always 0 here.

Replace `1/x` with `1.0/x` or `1f/x` and it should work.

Answer 2

Thank you Schindlabua....it worked!!!!
