Can't assign array according to formula

[extreme]

Hello, maybe someone can help me to figure out where is the mistake in this code? The array values are not what they should be according to formula.

#include<iostream>
#include<cmath>
using namespace std;
float A[999999];


int main ()
{
for (int i=0; i<=999999; ++i)
{
A[i]=(1/(i+1)); // Here is a mistake, A[i] values are wrong
}
}

Array elements start numbering at 0 and end at the array size less 1 (999998). You don't want the for loop to be inclusive of 999999 - that'll be an invalid element.

Even when i write

#include<iostream>
#include<cmath>
using namespace std;
float A[1000000];


int main ()
{
for (int i=0; i<=999999; ++i)
{
A[i]=(1/(i+1)); // Here is a mistake, A[i] values are wrong
}
}

the array values are wrong, for example
A[5]=0
when it should be according to formula
A[5]=1.66

Ah - you're getting an integer division result.

You can change 1 to 1.0 in the formula.

Thank you, that fixed it :)
