Thread: Flight program not outputting

Code:

Code:

 #include <iostream>
 using namespace std;
 #include "Flight.h"

 Flight::Flight(){
     num = 0;
     dest[0] = '\0';
 }
 
 Flight::Flight(int n, const char* d){
     if((n>-1) && (strcmp(d,'\0') == 1)){
               num = n;
               strcpy(dest,d);          
     }  
     else{
               num = 0;
               dest[0] = '\0' ;   
     }                 
 }
 
 Flight::~Flight(){
                   
 }
 
 Flight& Flight::width(int w){
     cout.width(w);
     cout << num << dest <<endl; 
     return *this;     
 }
 
 int Flight::number() const{
     return num;    
 }
 
 const char* Flight::destination() const{
     return dest;      
 }
 
 ostream& operator<<(ostream& os, const Flight& st){
     os << st.num << ' ' << st.dest << endl;
     return os;         
 }
 
 void display(Flight flight) {

     cout << flight.width(2) << endl;

 }

 int main ( ) {
     Flight f, g(857, "Toronto"); 

     cout << g.width(9) << endl;
     f = g;
     display(f);
     cout << f.number() << endl;
     cout << f.destination() << endl;
     return 0;
 }

Header:

Code:

class Flight{
             int num;
             char dest[15]; 
      public:
             Flight();
             Flight(int n, const char* d);
             ~Flight();
             const char* destination() const;
             int number() const;
             Flight& width(int); 
             friend ostream& operator<<(ostream& os, const Flight& s);  
};

I dont know what the problem is, but when i run this compiled it doesnt give any output.

'\0' is not a string and cannot be used in strcmp. Fortunately, "\0" is.
