Explanation / Answer

#include <iostream>
#include <string>
#include <cstring>
using namespace std;
int main()
{
std::string package;
std::string minsUsed;
double totalBill;
char x[5];
std::cout << "What is your package? ";
getline (std::cin, package);
std::cout << "What is your total minutes used? ";
getline (std::cin, minsUsed);
strcpy(x,package.c_str());

switch(x[0]){
   case 'A':
   if (atof(minsUsed.c_str()) <= 450 ) {
       totalBill = 39.99;
    }
   else {
   totalBill = 39.99 + (atof(minsUsed.c_str()) - 450 ) * 0.45;
   }
   break;
    case 'B':
   if (atof(minsUsed.c_str()) <= 900 ) {
       totalBill = 59.99;
    }
   else {
   totalBill = 59.99 + (atof(minsUsed.c_str()) - 900 ) * 0.40;
   }
   break;
   case 'C':
   totalBill = 69.99;
   break;
   default:
   cout << "Please enter correct package either A/B/C";
   return 1;
