I\'m trying to Implement a Logger class and add a Logger object to this ATM Clas

Question

I'm trying to Implement a Logger class and add a Logger object to this ATM Class using composition. I'm kind of stuck because I cannot seem to get anything working.

 

 

 

The log should be written to a text file on the hard drive and each entry should be appended to the file. Each Log entry should have a timestamp... The following classes should access the Logger: ATM, Withdrawal, Deposit, BalanceInquiry. Log all significant events such as Object creation & destruction, User Authentication failed/success, Execution of all ATM transaction types, etc...

 

 

 

Leave the user Authentication, I.E., the Account #'s and Pin $'s hard coded... A sample account:

 

 

 

Account #: 12345
Pin #: 54321

 

 

 

// What time is it?

// The Logger::Log() function will need this code

#include  

#include  

#include  

#pragma warning( disable : 4996)

 

using namespace std;

 

void main(void)

{ 

   // Test this first, then put it in Logger::Log()

   char buf[30];

   time_t rawtime;

   time(&rawtime);

   strcpy(buf, ctime(&rawtime));

   buf[strlen(buf) - 1] = 0;  // get rid of the LF

   cout << buf; 

}

Explanation / Answer

//Here is Log class implemented that can be used in other's class. #include #include using namespace std; class Logger { ofstream out; public: Logger(); // open the file in here void Log(char *); // log to the file here with a timestamp prefix ~Logger(); // close the file here }; Logger::Logger() { out.open("log.txt", ios::out | ios::app | ios::binary); } void Logger::Log(char *data) { if (out.is_open()) { char buf[30]; time_t rawtime; time(&rawtime); strcpy(buf, ctime(&rawtime)); buf[strlen(buf) - 1] = 0; // get rid of the LF cout
