I dont understand why if I put the "counter++;" line below the " term = term + (1.0/(counter*(counter + 1.0)));" line it gives me infinite? And when I place it above it it doesn't give me infinite? Why does this happen ?

Answer 1

#include <iostream>
using namespace std;

int main()
{
int n, counter=0;
double term=0;

cin >> n;

while (counter <= n)
{
counter++;
term = term + (1.0/(counter*(counter + 1.0)));


}

cout << term;

return 0;
}

Answer 2

initial value of counter = 0,

you're dividing the counter. thats the problem

Answer 3

change the initial value of counter to 1, it will work...
