Question

In c++ please!!

An office with six workers maintains a snack bar managed on the honor system. A worker who takes a snack records his or her ID number and the price on a list. Once a month, the snack bar manager enters the data into a computer program that calculates the monthly bill for each worker. No item at the snack bar costs more than $2, and monthly totals are usually less than $100.

(a) Write a complete specification for this program.

(b) Using a top-down development technique, write a main program that will call functions to generate

a monthly report. These functions are described here. Declare an array of floats named tabs to

store total purchase amounts for each member and the guests.

The purchases() function should have one parameter, the tabs array. This function should allow

the manager to enter two data items for each purchase: the price and the ID number of the worker who made the purchase. The ID numbers must be integers between 1 and 6. In addition, the code 0 is used for guests, whose bills are paid by the company. As each purchase is read, the amount (in dollars and cents) should be added to the array slot for the appropriate worker. When the manager enters an ID code that is not between 0 and 6, it should be considered a sentinel value and a signal to end the loop and return from the function. At that time, the array should contain the total purchases for each worker and for the guests.The bills() function should have one parameter, the tabs array. Print a bill for each worker, giving the ID number and the amount due

Thanks for the question.

Here is the completed code for this problem. Comments are included so that you understand whats going on. Let me know if you have any doubts or if you need anything to change.

Thank You !!

#include<iostream>
#include<iomanip>
using namespace std;

// takes in the float array and populate the amount
// keep asking the user to enter the purchase amount
// until the id is less than 0 or greater than 6
void purchases(float tabs[]){
  
   int id=0;
   float purchaseAmount=0.0;
   while(0<=id && id<=6){
      
       cout<<"Enter employee ID: (0 - guest, 1-6 for workers): ";
       cin>>id;
       if(0<=id && id<=6){
           cout<<"Enter purchase amount: $";
           cin>>purchaseAmount;
           tabs[id]+=purchaseAmount;
       }
   }
}

// takes in the tabs array and print the bill for each worker and guest
void printBill(float tabs[]){
  
   cout<<fixed<<showpoint<<setprecision(2);
   for(int id=0;id<7;id++){
      
       if(id==0)
       //cout<<"Guest. Total Purchase Amount $"<<tabs[id]<<endl;
       else
       cout<<"Worker"<<id<<" Total Purchase Amount $"<<tabs[id]<<endl;
   }
  
}

int main(){
  
   float tabs[7]{0.0}; // index 0 is for guest
   purchases(tabs);
   printBill(tabs);
}
