The vending machine C++ code has a problem.
I wanted to call the "tPrice" variable from the "chocoSelect" function to "insertCoin" function, but it does not work.
Same thing as for calling variables "cChoice, qAMB, qSD, qCS, qCMB, currentTotal" from the "chocoSelect" function to the "dispenser" function.
What should I include for the clrscr() to work?
#include <iostream>
#include <iomanip>
#include <cstdio>
#include <cmath>
using namespace std;
int main()
{
chocoSelect();
insertCoin();
dispenser();
system ("pause");
return 0;
}
void chocoSelect()
{
clrscr();
int cChoice; // Your chocolate selection.
int qAMB, qSD, qCS, qCMB; // Quantity of All Milk Bar, Sugar Drops, Caramel Surprise, and Chunky Milk Bar respectively.
double cPrice; // Current price for all chocolates.
double tPrice = 0.00; // Total price for all chocolates.
cout << "**************************************" <<endl;
