1. Print out the initial balance, and allow user to type-in the name and the price of item the user want to buy by sing prompt() function.

2. When user does not have enough money to buy an item, the program will print out this message:

You want to buy a tv for $500 Your current balance is $300 You do NOT have enough money!! =========================

3. Add confirm() message to ask if user wants to continue shopping or not. If yes, user will be able to type-in item and price again. If not, the program ends.

Here are program outputs:

Your starting balance is $1000 ========================= You bought a tv for $300 Current balance is $700 ========================= You bought a tv for $400 Current balance is $300 ========================= You want to buy a tv for $500 Your current balance is $300 You do NOT have enough money!! =========================
