c++ - using classes to create a coin toss program -


having trouble figuring out constructors code in main() supposed test class can go on rest of program. instructions constructors

this class has 2 constructors. default constructor (the 1 takes no arguments) should initialize value of coin penny (0.01) , side should initialized calling toss() method described below.

the other constructor takes 1 argument: double holds initial value coin. passed in argument should used initialize value of coin. no error checking required. side should initialized calling toss() method described below.

this code

#include <iostream> #include <iomanip> #include <cstdlib> #include <ctime> #include <cstring>  using namespace std;    //put coin class definition after line  class coin { public:   coin()   {   value = 0.01;   toss();    }    coin(double )   {   toss();       }    void toss();    int getside();   double getvalue();  private:   double value;    char side[6]; };           int main() { //set random number generator , formatting output  srand( 1 );  cout << fixed << setprecision(2);   //create objects using 2 constructors  coin coin1; coin coin2( 0.25 ); coin coin3( 0.10 );  //test 1: getside method  cout << "test 1: use getside method on of objects" << endl <<     endl      << "coin1 has " << ( (coin1.getside() == 1)? "heads" : "tails" ) << " up" << endl  << "coin2 has " << ( (coin2.getside() == 1)? "heads" : "tails" ) << " up" << endl      << "coin3 has " << ( (coin3.getside() == 1)? "heads" : "tails" ) << " up" << endl;  //test 2: getvalue method  cout << endl << endl      << "test 2: use getvalue method on of objects" << endl << endl      << "coin1 has value $" << coin1.getvalue() << endl      << "coin2 has value $" << coin2.getvalue() << endl      << "coin3 has value $" << coin3.getvalue() << endl;  //test 3: toss method  cout << endl << endl      << "test 3: use toss method 5 times on of objects" << endl << endl;  cout << "coin1       coin2       coin3" << endl      << "-----------------------------" << endl;  for( int cnt = 1; cnt <= 5; cnt++ )   {   coin1.toss();   cout << ( (coin1.getside() == 1)? "heads" : "tails" );    coin2.toss();   cout << ( (coin2.getside() == 1)? "       heads" : "       tails" );    coin3.toss();   cout << ( (coin3.getside() == 1)? "       heads" : "       tails" ) << endl;   }  return 0; }  //code constructors , methods coin class after line    void coin::toss()     {       int num = rand() % 2+ 1;     if (num == 1)     {         strcpy(side,"heads");      }        else         {             strcpy(side,"tails");        }    }  int coin::getside()     {       if (side=="heads")        {         return 1;         }        else         {         return 2;        }      }   double coin::getvalue()     {      return value;       }

finally figured out gave effort!

#include <iostream> #include <iomanip> #include <cstdlib> #include <ctime> #include <cstring>  using namespace std;    //put coin class definition after line  class coin { public:   coin();   coin(double );   void toss();    int getside();   double getvalue();   private: double value;    char side[6]; };  int main() { //set random number generator , formatting output  srand(  time(null) );  cout << fixed << setprecision(2);     //create objects using 2 constructors  coin coin1; coin coin2( 0.25 ); coin coin3( 0.10 );   double balance;    while (balance < 1.00)  { cout << "current balance: "<<balance<<endl;  coin1.toss(); cout<< "nickel: "<< ( (coin1.getside() == 1)? "heads" : "tails" )<<endl;  if (coin1.getside()==1)     {     balance +=coin1.getvalue();      }  coin3.toss(); cout<< "dime: " << ( (coin3.getside() == 1)? "heads" : "tails" )<<endl; if (coin3.getside()==1)     {     balance +=coin3.getvalue();      } coin2.toss(); cout<< "quarter: " << ( (coin2.getside() == 1)? "heads" : "tails" )<<endl; if (coin2.getside()==1)     {     balance +=coin2.getvalue();      } cout << "-----------------------------" <<endl << "your current balance $"<< balance <<endl << endl;    }   cout<< "the final balance "<< balance<<" congrats! won!"<<endl;   return 0;    }    //code constructors , methods coin class after line     void coin::toss()       {  int num = rand() % 2+ 1; if (num == 1) {     strcpy(side,"heads");  }    else     {         strcpy(side,"tails");    }   }   int coin::getside() {  if (strcmp(side,"heads")==true) { return 1; } else return 2; }   double coin::getvalue()     {      return value;   }  coin::coin() {   value = 0.05;   toss();   }  coin::coin(double newvalue) {  value = newvalue;    }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
