I'm writing a program that needs to have several functions. Other than main, one of them is a function called get_inputs. In get_inputs, the program will get information from the user, and then return all 4 of the values recieved to main.

I know that pointers need to be used here, so here is what I think needs to be done, but I know that it wont work.

First of all, I need to properly call the function in main. I also need to find out if the way that I've implemented the pointers is correct. I'm not sure what I need to put inside the braces in the userInput array. I don't even know if the format is correct. I've done some research, but it is really confusing for me. Could I get some help with both of these?

NOTE: there are more functions in the program, but they dont apply to this.

Code:#include <stdio.h> #include <stdlib.h> #include <math.h> /* Rows represent the months of the year, Columns represent the hours in a typical day */ #define NROWS 11 #define NCOLS 23 #define TRUE 1 #define FALSE 0 #define INSTALLATION_COST 2000 float panelEfficiency = 0.18, inverterEfficiency = 0.90; int main() { int houseEnergyREQ, numBatteries, numInverters; int flag = TRUE; float userInput[4], panelCost, inverterCost, batteryCost, panelArea, batteryRating = 4.8, inverterRating = 5.0, insolDayMin, maxHourPanelOutput, insolHourMax, totalCost; float *ptr_to_userInput; float insolation_Matrix[NROWS][NCOLS]; while(flag) { float get_inputs(float userInput[]); /* Switch userInput array to meaningful terms */ userInput[0] = houseEnergyREQ; userInput[1] = panelCost; userInput[2] = inverterCost; userInput[3] = batteryCost; /* Equation to calculate panelArea */ panelArea = houseEnergyREQ/(insolDayMin*panelEfficiency*inverterEfficiency); /* Equation to calculate maxHourPanelOutput */ maxHourPanelOutput = insolHourMax*panelArea*panelEfficiency; /* Equation to calculate numbatteries */ numBatteries = ceil(houseEnergyREQ/(inverterEfficiency*batteryRating)); /* Equation to calculate numInverters */ numInverters = ceil(maxHourPanelOutput/(inverterEfficiency*inverterRating)); /* Equation to calculate total cost */ totalCost = panelArea*panelCost + numBatteries*batteryCost + numInverters*inverterCost + INSTALLATION_COST; printf("The total cost of your Solar panel system is %.2f $. \n", totalCost); /* Give user an option to quit program */ printf("Do you wish to continue? (y/n) \n"); if(getchar() == 'n') { flag = FALSE; } } system("PAUSE"); } /*---------------------------------------*/ /* Function to get inputs houseEnergyREQ, panelCost, inverterCost, batteryCost */ float get_inputs(float userInput[4], *ptr_to_userInput) { *ptr_to_userInput = &userInput[] printf("This program will calculate the total cost of your solar panel system."); printf("Enter the daily required amount of energy for your house, in kWh : \n"); scanf("%f", &userInput[0]); printf("Enter the cost of solar panels (per m^2), power inverters and batteries: \n"); scanf("*f %f %f", &userInput[1], &userInput[2], &userInput[3]); return *ptr_to_userInput; }
