Question

A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor will be required. The company charges $20.00 per hour for labor. Write a program that allows the user to enter the number of rooms to be painted and the price of the paint per gallon. It should ask for the square feet of wall space in each room. The program should have methods that return the following data:
Create pseudocode and C code.
- The number of gallons of paint required
- The hours of labor required
- The cost of the paint
- The labor charges
- The total cost of the paint job

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>

// Function Declarations
double costOfPaint(double paint_required, double price);
double totalCost(double cost_of_paint, double labor_charges);
double calLaborCharges(double hours);
double paintReq(int wall_space);
double hoursOfLabor(int wall_space);

int main() {
  
// Declaring variables
int wall_space;
double price;
// Getting the wall space
printf("Enter the wall space in square feet:");
scanf("%d",&wall_space);
// Getting the price of the paint per gallon entered by the user
printf("Enter the Price of paint per gallon:");
scanf("%lf",&price);
// Calling the functions
double paint_required = paintReq(wall_space);
double cost_of_paint = costOfPaint(paint_required, price);
double hours = hoursOfLabor(wall_space);
double labor_charges = calLaborCharges(hours);
double tot_cost = totalCost(cost_of_paint, labor_charges);
// Displaying the results
printf("Gallons of paint: %.2f\n",paint_required);
  
printf("Hours Of labor : %.2f\n",hours);
printf("Paint Charges :$ %.2f\n",cost_of_paint);
printf("Labor charges :$ %.2f\n",labor_charges);
printf("Total cost :$ %.2f",tot_cost);
  
  
  
   return 0;
  
}

// Function which calculate the cost of paint
double costOfPaint(double paint_required, double price)
{
return paint_required * price;
}
// Function which calculate the total cost
double totalCost(double cost_of_paint, double labor_charges)
{
return (cost_of_paint + labor_charges);
}
// Function which calculate the labor charges
double calLaborCharges(double hours)
{
return hours * 20;
}
// Function which calculate the hors of labor required
double hoursOfLabor(int wall_space)
{
return ((double)wall_space / 115) * 8;
}
// Function which calculate the no of gallons of paint required
double paintReq(int wall_space)
{
return (double)wall_space / 115;
}
