amateur programmer here looking for some pretty basic help from the community. I am completing a program which is supposed to calculate the total monthly/annual cost for a vehicle; mind you, it's meant to be simple, but I probably shoot myself without noticing...
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
using std::ios;
using std::fixed;
#include <cmath>
using namespace std;
int main()
{
//variable declaration
double loanmonthlyfee;
double totalmonthlybill
double insurancecost;
double totalannualcost
double additionalcosts;
double gasolineexpenditure;
double tiremaintenance;
//input
cout <<"Enter Loan Monthly fee.";
cin >> loanmonthlyfee;
cout<<"enter insurance cost.";
cin >>insurancecost;
cout <<"enter gasoline expenditure.";
cin >> gasolineexpenditure;
cout <<"enter tire maintenance cost";
cin >> tiremaintenance;
cout <<"enter any additional costs";
cin >> additionalcosts;
double totalmonthlybill = loanmonthlybill + insurancecost + totalannualcost + additionalcosts + gasolineexpenditure + tiremaintenance;
double totalannualcost = totalmonthlybill * 12;
cout <<"your total monthyl bill is" << totalmonthlybill;
cout <<"your total annual bill is" << totalannualcost;
system("PAUSE");
return 0;
}
