//  SkyDivers.cpp:    Calculating Velocity of a Falling Body
//
//  Programmer:   Bill McQuain
//  Compiler:     Visual C++ 2008
//  Date:         June 12, 2009
//
//  Purpose:
//    To compute the velocity of a free-falling body, given
//    the number of seconds since its release, its weight, 
//    and its coefficient of drag.
//
//  Modified June 09 to use a functional decomposition.
//
//  This file contains an edited version of my completed solution; many things
//  have been cut out, including:
//
//    - some global declarations
//    - all of the function declarations
//    - the parameter lists in the function calls; but the calls themselves
//      are still shown
//    - the function implementations (of course)
//

int main() {

//  Declarations:
   string lastName,
          firstName;
   double Weight,        // weight of object in pounds
          Mass,			 // mass of object
          Drag,			 // coeff of drag for object
          Time,			 // seconds object has been falling
          fpsV,			 // object velocity in feet per second
          mphV;			 //        and miles per hour

   ifstream iFile("Input.txt");             // open input file
   ofstream oFile("Output.txt");            // open output file
   oFile << fixed << showpoint;             // prepare for floating-point output

//  Print the header info to output file:
   printTableHeader(. . .);

//  Read first line of data from input file:
//
   iFile.ignore(INT_MAX, '\n');				// skip header lines
   iFile.ignore(INT_MAX, '\n');
   
   readTableRow(. . .);

//  Process lines of data until none remain:
//
   while (iFile) {
      // ----------------------------------------------------------- Processing Section
      // create full name for printing (optional):
	   string Name = firstName + " " + lastName;
	   
	   // calculate mass, using specified formula:
	   Mass = calculateMass(. . .);

	   // calculate velocity in feet per second, using specified formula:
	   fpsV = calculateFPS(. . .);

	   // convert velocity to miles per hour:
	   mphV = calculateMPH(. . .);

      // --------------------------------------------------------------- Output Section
	   // print mass, drag, time and velocity as per the project spec:
      printTableRow(. . .);

      //  Try to read the next line of input:
      //
      readTableRow(. . .);

   }                                   // End of while loop.

   printTableFooter(. . .);

   //  Close the files:
   iFile.close();
   oFile.close();
   //  Exit program:
   return 0;
}
