# Cougar Cash

## Problem Statement

• Everyday you go to the BYU Candy Counter and buy chocolate covered cinnamon bears using your Cougar Cash card.
• Write a program which prompts the user how much they want to spend on candy, and then prints out the card balance and what cash is still owed.
• The initial card balance is $10.00. • Any purchase greater than what is on the card should use up the balance on the card. ## Solution /* Test Case 1: Input: 8.50 (input less than initial balance) Output: balance is 1.50 Actual: balance is 1.50 Test Case 2: Input: 15.00 (input greater than initial balance) Output: balance is 0, owes 5.00 Actual: balance is 0, owes 5.00 Test Case 3: Input: 0 (border case) Output: balance is 10 Actual: balance is 10 */ #include <iostream> #include <iomanip> #include <string> using namespace std; const double INITIAL_BALANCE = 10.00; int main() { // inputs: how much they want to spend // outputs: balance after purchase, cash owed cout << fixed << setprecision(2); // Prompt the user double desired_expenditure; double balance = INITIAL_BALANCE; cout << "How much you wanna spend on bears?$";
cin >> desired_expenditure;

// if input > balance
if (desired_expenditure > balance)
{

// report (input - balance) as still owed
cout << "$" << (desired_expenditure - balance) << " is still owed" << endl; // update balance to 0 balance = 0; } // otherwise else { // balance = balance - input balance -= desired_expenditure; } // print balance cout << "Your new balance is$" << balance << endl;

system("pause");
return 0;
