Thread: Need help with my first program

enrolled in my first c++ class and have a homework assignment due. my problem is that i declared my variables and wrote what i think is a good start for the program. my problem is that when i enter the information that i want, my actual output does nothing. i cant seem to get my program to do the math it is supposed to. can someone look at this and see what i am missing. this is just part of the project. i want to get on the right track before i write the rest. i just want this to figure the old monthly cost. i use Dev C++. thank you.

Code:

#include <iostream>
#include <cstdlib>
#include <cfloat>

using namespace std;

int main(int argc, char *argv[]) {


float CostOfNewCar; //New vehicle price
float MonthlyMilesDriven; //Mile driven per month
float NewVehicleMPG; //New vehicles mile per gallon of gas
float OldVehicleMPG; //Old vehicles miles per gallon of gas
float CurrentMonthlyCost; //Current monthly cost that a persons spends
float ProposedMonthlyCost; //Proposed monthly cost that person will spend
float PriceOfGas; //Enter the current price of gas per gallon
float NewCarPayment; //New car payment cost
float OldMonthlyGasExpense; //Old vehicle gas expense per month
float NewMonthlyGasExpense; //New vehicle gas expense per month
float OldCarPayment; //Old car payment

// Prompt user for information

cout << "How many mile do you drive a month?:" ;
cin >> MonthlyMilesDriven;

cout << "Current vehichles MPG :" ;
cin >> OldVehicleMPG;

cout << "How much is gas per gallon:" ;
cin >> PriceOfGas;








// Calculations

NewCarPayment = CostOfNewCar / 60 ;
OldCarPayment = 130.00;
OldMonthlyGasExpense = MonthlyMilesDriven / OldVehicleMPG * PriceOfGas;
CurrentMonthlyCost = OldMonthlyGasExpense + OldCarPayment;





// Output results

cout << "Currently monthly cost: ";
cin >> CurrentMonthlyCost;







system("pause");


return(0);
