Foundations Of Computer Science (COP 3014)

The files will be at the bottom of the page. The cryptoaccount.cpp, cryptoaccount.h, and the cryptoaccountmain.cpp files are in C++ format, they need to be converted to a CLASS format using the guidelines below.

The cryptobroker.cpp file is as follows:

/*

* The program implements and shows how to use following functions

* Sell coins: let us say that somebody else has provided you with a C function:

* bool sell(double qty);

* Buy coin: The function available to you is bool buy(double qty);

* Check Price: double checkPrice() Will return the current market price of the currency.

*/

#include "cryptobroker.h"

double sell(double quantity){

return quantity * currentPrice;

}

double buy(double quantity){

return quantity * currentPrice;

}

double checkPrice(){

//sleep(1);

//srand(time(NULL));

return currentPrice = 1000 + (0.5 - ((double) rand())/RAND_MAX)*RANGE;

}

void print(){

cout

}

void test()

{

// for(int i = 0; i

// checkPrice();

// print();

//}

The cryptobroker.h file is as follows:

Problem We will convert the code for HW2 into a C+ class. In the class we have discussed a (very) incomplete stock trading code. (What are Requirements, Function Specifications and Design2) Requirements In this problem, we will develop a cryptocurrency trading application. Background Currently the three most popular cryptocurrencies are: Bitcoin: Symbol BTC Ethereum: Symbol ETH Rippl Symbol XRP The concept is the same as trading stocks. You want to buy when the price is low, and sell when the price is high to make a profit. For professors and students it only makes sense to trade a fraction of a coin at a time
