Unable to send value from function back to main

[wasey]

I'm not sure where my error is, can someone steer me in the right direction? I have to calculate the distance an object travels due to gravity based on how long the object falls. I'm unable to return a value to main and I only get the output "The object traveled 0.0 meters." Thanks!

#include <iostream>
#include <iomanip>
using std::cout;
using std::cin;
using std::endl;
using std::showpoint;
using std::fixed;
using std::setprecision;

//Function prototype for formula
double fallDistance(double time);

int main()
	{
	double distance;
	double time;

	//set output to show one decimal place
	cout << fixed << showpoint << setprecision(1);	
	cout << "How long did the object fall? \n";
	cin >> time;
	cout << "The object traveled " << distance << " meters." << endl;

	return 0;
	}
double fallDistance(double time)
	{
	double distance;
	const double grav = 9.8;

	distance = (1/2) * grav * (time * time);
	return distance;
	}

in main write just before line 22

distance = fallDistance( time);

as in:

nt main()
	{
	double distance;
	double time;

	//set output to show one decimal place
	cout << fixed << showpoint << setprecision(1);	
	cout << "How long did the object fall? \n";
	cin >> time;
        distance = fallDistance(time);
	cout << "The object traveled " << distance << " meters." << endl;

	return 0;
	}

Also, in fallDistance(), change (1/2) to (1.0/2).

1/2 divides integers, so it uses integer division which truncates the answer (0.5) to an integer (0).

Thank you all, I was banging my head on this one. Appreciate it!
