I am looking to split my single-function C++ business calculator program into numerous functions. For example, separating the recurring parts of the code, such as when the program asks the user the costs of meals, fees, etc.
1. My goal is to not have any functions exceeding 20 lines.
My code:
#include
using namespace std;
int main(int argc, const char * argv[]) { //Command line arguments. 'argc' is argument count; it stores how many arguments that will be passed onto the main function of the program. 'argv' is argument vector' and it stores the array information. These are in this program as they are what pass the main values into the main function of the program.
int conti=0; //This line is for later on in the program when the user is asked whether or not they wish to use the calculator again, or quit. 'continue'
do{
std::cout
int daysOfTrip;float totalcost=0;
cin>>daysOfTrip;
int parkingfee[daysOfTrip],hotelFee[daysOfTrip-1]; //Minus one as hotel stays are one day shorter than a day trip. example: 3 day trip is 2 hotel nights.
int breaks[daysOfTrip],lunch[daysOfTrip],dinner[daysOfTrip]; //All mealtimes coincide with the days within the trip.
for (int i=0; i
breaks[i]=0;lunch[i]=0;dinner[i]=0;
}
int employeePaid = 0;
cout
float arrivalTime,deptTime,airfare,confOrSemRegFee;
cin>>deptTime;
cout
cin>>arrivalTime;
cout
cin>>airfare;
totalcost+=airfare;
cout
cin>>confOrSemRegFee;
totalcost+=confOrSemRegFee; //total cost equals 'total cost' plus 'conference or seminar fee'.
cout
int rentalOrTaxi=0;
do{

cin>>rentalOrTaxi;
if(!(rentalOrTaxi==1 || rentalOrTaxi==2)){cout
}while(!(rentalOrTaxi==1 || rentalOrTaxi==2));

int rentalFee=0;
float gasFee = 0;
if(rentalOrTaxi==1){
do{
