9.1 topic: Call to Constructors

#include <iostream>#include<cstring>using namespacestd;classgolf{stringM_name; intM_handicap;  Public: Golf (): M_name ("Sam"), M_handicap ( -){};//assignment of destructors, M_name and M_handicap are initialized before entering curly braces            voidShow () {cout<< M_name <<','<< M_handicap <<Endl; } Golf (stringNameintHandicap) {M_name=name; M_handicap=Handicap; }            };intMain () {Golf one; Golf ("Tonny",10086);    One.show (); Two.show ();}

Just use string and try to use strcpy to assign a lot of trouble.

Above is actually the answer of 10.1, the following is 9.1

Total Golf.h, golf.cpp,9-1golf.cpp three files

Golf.h header file:

1 //golf.h2 Const intLen = +;3 structGolf4 {5  CharFullname[len];6  intHandicap;7 };8 //non-interactive version9 //function sets golf structure to provided name, HandicapTen //using values passed as arguments to the function One voidSetgolf (Golf & G,Const Char* Name,inthc); A //Interactive version - //function solicits name and handicap from user - //and sets the members of the G to the values entered the //returns 1 if name is entered, 0 if name is empty string - intSetgolf (Golf &g); - //function resets handicap to new value - voidHandicap (Golf & G,inthc); + //function displays contents of golf structure - voidShowgolf (ConstGolf & G);

Golf.cpp:

1 //Golf.cpp2#include <iostream>3#include"golf.h"4#include <cstring>5 //function solicits name and handicap from user6 //returns 1 if name is entered, 0 if name is empty string7 intSetgolf (Golf &g)8 {9Std::cout <<"Please enter golfer ' s full name:";Ten std::cin.getline (G.fullname, Len); One      if(g.fullname[0] ==' /') A      return 0;//Premature termination -Std::cout <<"Please enter Handicap for"<< G.fullname <<": "; -       while(!

9-1golf.cpp:

//9-1golf.cpp#include <iostream>#include"golf.h"//link with golf.cppConst intMems =5;intMainvoid){     using namespacestd;    Golf Team[mems]; cout<<"Enter up to"<< Mems <<"Golf Team members:\n"; inti;  for(i =0; i < Mems; i++)     if(Setgolf (team[i]) = =0)      Break;  for(intj =0; J < I; J + +)//If it terminates prematurely, it can be run as an existing input. Showgolf (Team[j]); Setgolf (team[0],"Fred Norman",5); Showgolf (team[0]); Handicap (team[0],3); Showgolf (team[0]); return 0;}

Three files are compiled in a project.
