to check condition that ans must be below 1 and to calulate pmf

as I can see that function (fact) always returns a value of 1.0

may be it should evaluate the factorial value of f ? (f * f1 * f2 *...*1)
 one year ago

nick67 Group TitleBest ResponseYou've already chosen the best response.1
in that case you should have: float fact(int f) { float s=1.0; while(f>0) { s=s*f; f; } return s; }
