problem with structure, and parameter passing.

[Clayfer]

My teacher marked off for the structure matching specs and correct parameter passing


COP 2220Project 250 pointsDue electronically Friday, 2-17, at 8:00 a.m. Preliminary structure and IPO chart due Monday, February 6NOTE: From now on, the first output of all programs you write should be your name.Modify your program from Project 1 into a modularly designed program. Inaddition to the previously specified calculations, the program should alsocalculate the Kelvin temperature from the Fahrenheit (or more easily, the Celsius) and the feet to inches. Use a six-column report as shown in the example output.Display floating point values in the report using 3 places of precision. Kelvin should be double but inches should be int. Create the report with decimal places aligned correctly with the implied decimal of the integers. The resulting program *must* match the structure chart listed below.

    calcTemp  calcDistance  calcWeight

and calcWeight *must* match the following prototype exactly. double calcWeight(int pounds);These requirements are worth significant points.This program is somewhat overmodularized but is an exercise in the different ways to pass data throughout functions in a program.

#include <stdio.h>
 
void getInput (int* pFahr, int* pFeet, int* pLbs);
void calcTDW (int fahr, int feet, int lbs);
void calcTemp (int fahr, double* pCels, double* pKelvin);
void calcDistance (int feet, double* pMeters, int* pInches);
double calcWeight (int lbs);
void display (int fahr, double cels, double kelvin, int feet, double 
              meters, int inches, int lbs, double kilos);
 
int main (void)
{
   printf("Name: Bryan Benson");
   printf("\n\n");
   int fahr, feet, lbs, inches;
   double cels, meters, kilos;
   double kelvin;
 
   getInput (&fahr, &feet, &lbs);
   calcTDW (fahr, feet, lbs);
   calcTemp (fahr, &cels, &kelvin);
   calcDistance (feet, &meters, &inches);
   kilos = calcWeight (lbs);
   display (fahr, cels, kelvin, feet, meters, inches, lbs, kilos);
 
   return 0;
}
 
void getInput (int* pFahr, int* pFeet, int* pLbs)
{
   printf ("Enter an integer value for Fahrenheit : ");
   scanf ("%d", pFahr);
   printf ("\nEnter an integer value for Feet : ");
   scanf ("%d", pFeet);
   printf ("\nEnter an integer value for Pounds : ");
   scanf ("%d", pLbs);
   printf ("\n\n");
}
 
void calcTDW (int fahr, int feet, int lbs)
{
   void calcTemp (int fahr, double* pCels, double* pKelvin);
   void calcDistance (int feet, double* pMeters, int* pInches);
   double calcWeight (int lbs);
}
 
void calcTemp (int fahr, double* pCels, double* pKelvin)
{
   *pCels = 5.0 * (fahr - 32) / 9.0;
   *pKelvin = *pCels + 273;
}
 
void calcDistance (int feet, double* pMeters, int* pInches)
{
   *pMeters = 0.3048 * feet;
   *pInches = 12 * feet;
}
  
double calcWeight (int lbs)
{
   double kilos;
  
   kilos = lbs / 2.204;
 
   return kilos;
}
 
void display (int fahr, double cels, double kelvin, int feet, double
              meters, int inches, int lbs, double kilos)
{
   printf ("\n  Original       Value  Converted to      Value  ");
   printf ("Converted to     Value    ");
 
   printf ("\n  --------       -----  ------------      -----  ");
   printf ("------------     -----    ");
 
   printf ("\nFahrenheit");
   printf ("%12d", fahr);
   printf ("       Celsius");
   printf ("%11.3f", cels);
   printf ("        Kelvin");
   printf ("%14.3f", kelvin);
 
   printf ("\n      Feet");
   printf ("%12d", feet);
   printf ("        Meters");
   printf ("%11.3f", meters);
   printf ("        Inches");
   printf ("%10d", inches);
  
   printf ("\n    Pounds");
   printf ("%12d", lbs);
   printf ("     Kilograms");
   printf ("%11.3f", kilos);
   printf ("\n\n");

What is your question?

Well the basic problem is that your main is doing all the work of calculating, and that you didn't move all those calc.... calls into calcTDW.
