Time Intervals

Feb 9, 2013 at 9:16pm

HI I'm trying to write a program that reads the height of a tower and how long it would take an object to hit the ground. I think most of my code is correct but I'm getting a few errors.

#include<iostream>
#include<iomanip>
#include<cmath>
using namespace std;

void GenerateTable(float, float);

int main()
{
	float towerHeight;
	float deltaT;

	cout<<"Enter tower height in meters: ";
	cin>>towerHeight;
	cout<<"Enter the time intervals you would like: ";
	cin>>deltaT;
	cout<<endl;

	return 0;
}
void GenerateTable (float towerHeight, float deltaT)
{
	const float g =9.80655;
	float objectHeight;
	float t;

	cout<<setw(10)<<"Time"<<setw(9)<<"Height"<<endl;
	t=0.0;
	objectHeight = towerHeight;

	//display table
	cout.setf(ios::fixed);
	while (objectHeight>0)
	{
		cout<<setw(9)<<setprecision(2)<<t<<setw(10)<<objectHeight<<endl;
		t+=deltaT;
		objectHeight=towerHeight-0.5*g*pow(t,2);
	}//end while

	//object hits the ground.
	cout<<endl<<"SPLAT!!!"<<endl<<endl;

Edit & run on cpp.sh

The errors I'm getting are:
warning C4305: 'initializing' : truncation from 'double' to 'const float'
warning C4244: '=' : conversion from 'double' to 'float', possible loss of data
fatal error C1075: end of file found before the left brace '{'

Any help and explination would be great, Thanks.

you are missing } brace at the end of program and than you never called GenerateTable(float, float) function in the main function...

Ok I got it to let me input my height and time intervals but now it exits when i press enter. where should I put my pause function?

write
system("pause");
before
return 0;

Thanks, that worked but, now the program pauses before it can calculate and display the table
