C++ Help needed! http://screencast.com/t/m9ddkmpqH 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 ?

    #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; }

    initial value of counter = 0, you're dividing the counter. thats the problem
