Solution

Code:

#include<iostream>

#include<math.h>
#include<fstream>

using namespace std;

const float INCHES_PER_FT = 12.0;
const float PI = 3.14159265;

void convertDimensions(float *,float *);
float calcSurfArea(float,float);
void computeCost(float *,float *,float *,float,float,float,float);
void printResults(float,float,float);

int main(){
  
   float height;   // height of the cone in inches.
   float diInches;   //Diameter of base of cone in inches.
   float rPrice;
   float gPrice;
   float bPrice;
   float radius;
   float surfaceArea;
   float redCost;
   float blueCost;
   float greenCost;
   ifstream inData;
  
   cout<<fixed<<showpoint;
   inData.open(\"C:/Users/user/Desktop/chegg/content.txt\");
   if(!inData){
       cout<<\"** can\'t open file\"<<\"**\"<<endl;
       return 1;
   }
   inData>>height>>diInches>>rPrice>>bPrice>>gPrice;
   convertDimensions(&height,&diInches);
   radius = diInches/2;
   surfaceArea = calcSurfArea(height,radius);
   cout<<\"Surface Area : \"<<surfaceArea<<endl;
   computeCost(&redCost,&blueCost,&greenCost,surfaceArea,rPrice,gPrice,bPrice);
   printResults(redCost,greenCost,blueCost);
   return 1;
}
void convertDimensions(float *height,float *diInches){
   *height = *height / INCHES_PER_FT;
   *diInches = *diInches / INCHES_PER_FT;
}
float calcSurfArea(float h,float r){
   float sArea;
   sArea = (PI * r) * (r + sqrt((h*h))+(r*r));
   return sArea;
}
void computeCost(float *redCost,float *blueCost,float *greenCost,float sArea,float rPrice,float gPrice,float bPrice){
   *redCost = sArea * rPrice;
   *greenCost = sArea * gPrice;
   *blueCost = sArea * bPrice;
}
void printResults(float redCost,float greenCost,float blueCost){
   cout<<\"Red paint cost : \"<<redCost<<endl;
   cout<<\"Green paint cost : \"<<greenCost<<endl;
   cout<<\"Red paint cost : \"<<blueCost<<endl;
