float fact(int f)

int i;
float s=1.0;
for(i=f;i>0;i)

Best ResponseYou've already chosen the best response.1hi thangeram, what's the purpose of fact function ?

Best ResponseYou've already chosen the best response.0to check condition that ans must be below 1 and to calulate pmf

Best ResponseYou've already chosen the best response.1as I can see that function (fact) always returns a value of 1.0

Best ResponseYou've already chosen the best response.0hmm your correct but nick tell me why it is not giving satisfying output

Best ResponseYou've already chosen the best response.1I don't know what the "fact" function should do on its input f

Best ResponseYou've already chosen the best response.0#include <stdio.h> #include <math.h> /* protype of "e", exp(x) == exp^x */ #include <conio.h> /* For clrscr() */ double Factorial1 (double a) { double answer = 1.0; while(a>1) answer *= a; return answer; } int main(void) { double result, res1, res2; double i = 0.0, k = 0.00; double answer = 0.0; result = res1 = res2 = 0.0; /* makes it easier to see input prompts */ printf("Enter mean: "); scanf("%lf", &i); printf("Enter value of interest: "); scanf("%lf", &k); /* factorial of value of interest */ answer = Factorial1(k); /* formula for k */ result = pow(i,k); res1 = 1/(exp(k)); res2 = (result * res1) / answer; printf("answer is ... : %0.20lf", res2); return 0; }

Best ResponseYou've already chosen the best response.1may be it should evaluate the factorial value of f ? (f * f1 * f2 *...*1)

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