Find diameter from volume of sphere C++ -


this question has answer here:

i have got task create program calculates diameter of sphere of volume 1234.67 cu meters.

i have written following code : - 

#include <iostream> #include <math.h>  using namespace std;  int main(){     float vol, dm, h;     vol = 1234.67;     cout << "calculating diameter of sphere volume 1234.67 cu meters" << endl;     h = vol*(3/4)*(7/22);     dm = 2 * cbrt(h);     cout << "the diameter of sphere volume 1234.67 cu meters " << dm << endl;     return 0; }

what's wrong program , gives 0 output

calculating diameter of sphere volume 1234.67 cu meters                                                                                                              diameter of sphere volume 1234.67 cu meters 0  

h = vol * (3 / 4) * (7 / 22);

should be

h = vol * (3.f / 4.f) * (7.f / 22.f);

as int 3 / 4 == 0.
