Question

C++

Write the code for the following procSale function. Its purpose is to take the array of Vendltem structures (first argument), the selection (2nd argument, which is also the array item to purchase), and the cash (3rd argument, which is the amount offered to pay for the item) and produce the following results: .If the cash is more than $1.00, output the message "Cash amount too large!" and return. If the cash is less than the price of the item selected, output the message "Not enough cash!", and return. · If there are no items left for the selection, output “No XXXXX left!" and return. If the cash is-or > price of the item selected, and there are items available for the selection ?Output the message: "XXXXXX purchased, your change is 0.YY" (where XXXXX is the drinkname and OYY is the change) Subtract 1 from the number of items available for the selection Assume you have the following global declarations for a Vendltem given: struct VendItem string itemName; double price; //all prices are int numLeft; 1.00 and multiples of ·05 3; const int SIZE-8; void procSale(VendItem vendInfo[SIZE], int selection, double cash)

Answer 1

#include <iostream>

using namespace std;
const int SIZE=8;
struct ventItem{
string itemName;
double price;
int numLeft;
};
void proSale(ventItem vendInfo[SIZE],int selection,double price){
// checking for cash
if(price>1){
cout<<"Cash amount to large"<<endl;
return;
}
// checking for cash availability
if(price<vendInfo[selection].price){
cout<<"Not enough cash"<<endl;
return;
}
// checking for items availability
if(vendInfo[selection].numLeft<1){
cout<<"No "<<vendInfo[selection].itemName<<" Left"<<endl;
return;
}
price=price-vendInfo[selection].price;
vendInfo[selection].numLeft--;
cout<<vendInfo[selection].itemName<<" purchased ,your change is "<<price<<endl;

int main(){
ventItem i1[]={
{"Bananas",0.10,2},
{"keer",0.15,1},
{"Almonds",0.05,1},
};
proSale(i1,1,0.5);
proSale(i1,1,0.5);
proSale(i1,0,0.08);
