C++ Program to Implement Trading Application

Prerequisite:

• Basic operators in C++
• Switch Case 
• Vector in C++
• Class and Objects in C++

Trading is a primary economic concept that involves buying and selling goods and services, along with compensation paid by a buyer to a seller. Trading applications in C++ can be a good example of understanding the basic concepts of C++. Also, It can act as a mini-projects for beginners, which can help them to enhance the concepts of C++ and also can build up their resume in the initial stage.

Problem Statement:

Build a Program in C++ forTrading applications where the operations performed are given below:

1. Get account Information 
2. Deposit Money
3. Withdraw Money
4. Buy Cryptocoins
5. Sell Cryptocoins
6. Check Transactions

Operations to be Performed

Trading includes knowledge about the profit loss and currencies. So the variables of the program will be as follows:

1.  Balance of user
2.  Profit Loss checker
3.  Bitcoins and Dogecoin
4.  Choice
5.  Withdraw amount
6.  Predict
7.  Total equity

Now about the Operations, we will be Performing:

1. Get Account Information:

In this operation, we will Just print the information about the user account. i.e. all the variables we have to observe are profit-loss, currencies, amount, etc.

2. Deposit Money:

In deposit, we can deposit money in our account.

3. Withdraw Money:

In withdrawal, we can withdraw the money we have in our account.

4. Buy Cryptocurrencies:

We will buy crypto using this operation. We can buy either Bitcoin or Dogecoin depending on our needs. 

5. Sell Cryptocurrencies:

We will sell crypto and add the amount we get after selling to our account.

6. Check Transactions:

In this Operation, we will print all the transactions performed till now.
