Establishing a for loop in functions

[snakeman413]

Hi. I need to establish a for loop or at least a loop that will help me repeat a program 5 times while utilizing functions. My problem is any time I try to establish the loop in proximity to where it normally works, I get a variety of errors messages. Any help would be greatly appreciated.

#include <iostream>
using std::fixed;
using std::cout;
using std::cin;
using std::endl;

#include <iomanip>
using std::setprecision;

#include <stdlib.h>

double discountFunction (double, double);
double finalCostFunction(double, double, double, double, const double, double, double, const double, double, double, const double); 
void displayWelcome ();

The problem you have is on line 111. You declared a statement outside of any function and since all you wanna do is repeat the functions 5 times. Just remove line 111 and put it on line 66, such that you have

displayWelcome();

//House choice
for( int i = 1; i <= 5; i++ ){
displayhouseOption(choice);

//extra bedrooom choice
bedroomOption(House_Square_Footage, BEDROOM_SIZE);

//deck choice
deck = deckchoice(optionalFeatures, WOODEN_CHOICE);

//counter top choice
cabinets = cabinetchoice(optionalFeatures, DELUXE_CABINETS); 

//interior choice
interior = interiorchoice(optionalFeatures, WOOD_CHOICE, BRASS_FIX, CERAMIC_TILES, DELUXE_SAUNA);

//discount
discount = discountFunction(discount, optionalFeatures);

//Calculate
totalHomeCost = finalCostFunction(House_Square_Footage, netHomeCost, totalHomeCost, basicHomeCost, profit, COST_PER_SQUARE_FT, optionalFeatures, PERCENT_PROFIT, discount, taxes, STATE_TAX_RATE); 

//Display result     
displaySummary(basicHomeCost, optionalFeatures, discount, totalHomeCost);

//Display end
displayNumberDone(i);

}

//Display goodbye
displayGoodbye();
     
return 0;

}//end of the main function

Since I don't know what functions you want in the loop, I simply placed it just before the call to displayGoodbye(); . Now that should make your code work.
