Need help creating an equation in C++ to calculate total -


my updated code. when run code keeps outputting prices of packages instead of 1 ask for. 

#include <iostream> using namespace std;  int main() {  // keep simple int choice_a = 995; int choice_b = 1995; int choice_c = 3995; char choice; int message_units, x=1; double price; bool selected = false;  // loop shows options { cout << "which package choose (enter a, b or c)" << endl; // need check cin >> choice; // keeping simple if (choice == 'a') { price = choice_a; selected = true; } else if (choice == 'b') { price = choice_b; selected = true; } else if (choice == 'c') { price = choice_c; selected = true; } cout << endl; } // loops until selected while (selected == false);  do{ cout << "how many message units (enter 1 - 672)" << endl; // again check cin >> message_units; x++; } while(x<2);  if(message_units > 5){ choice_a += 100 * (message_units - 5); } cout << "your total cost " << choice_a /100 << "." <<choice_a%100 endl if(message_units > 15){   choice_b += 50 * (message_units - 15);  } cout <<"yourtotalcostis"<<choice_b /100 << "." << choice_b%100<<endl;

(you missed "i" or two, english difficult non-native speaker.)

atotalcost = 9.95; if(messageunits>5)   atotalcost += 1.0 * (messageunits-5);

edit:

there several ways deal amounts of money. 1 of them store amount number of cents, print out care. example, amount $2.34 stored int price = 234, print out print price/100 (which 2), decimal point, price%100 (which 34, '%' modulo operator, can up). code this:

#include <iostream> using namespace std; int main() {   int messageunits;   cout << "how many message units(enter 1 - 672)" << endl;   cin >> messageunits;    int atotalcost = 995; // cost of package a, in cents   if(messageunits > 5){     atotalcost += 100 * (messageunits - 5);   }    cout << "your total cost " << atotalcost/100 << "." << atotalcost%100 << endl; }

there still work do, start.
