Question

I am working on a project for a class and I am having trouble with the output of the geometric mean, which always come out to be 1 and I’m sure that isn’t right.

Here’s my code:

#include<iostream>

#include<math.h>

using namespace std;

int main(int argc, char**argv) 
{
float i, j, k;
float a, h, g;

cout<<"Enter 3 floating point numbers"<<endl;
cin>>i>>j>>k;

while(i>0 && j>0 && k>0 )
{
    a = (i+j+k)/3;
    h = 3/((1/i) + (1/j) + (1/k));


    g = pow((i*j*k),(1/3));

    cout<<"Arithmetic: "<<a<<endl;
    cout<<"Harmonic: "<<h<<endl;
    cout<<"Geometric: "<<g<<endl;

    cout<<"Enter 3 floating point numbers"<<endl;
    cin>>i>>j>>k;
}


return(0);
}

Answer 1

1/3 is an integer equal to 0. You should write 1.0/3.0 (or 1./3) to get a floating point value.
