Question

Programming language is C++. Code must include exception-handling framework too. Show code and output when done.

Many national flags are very similar except for the colors . write a class Scandinavian_flag that can construct the flags of Denmark, Finland, and Sweden, and a main which creates each flag like this: Scandinavian_flag Denmark{white, red}; and so on, and draws all three flags with the country name underneath. Name your progam hw6pr3.cpp. Note: Don 't worry about any variations in the proportions of the different flags, just make the flags recognizable as belonging to that country.

Explanation / Answer

#include <iostream>

using namespace std;
class Scandinavian_flag
{
private:
int flag_color[3];
const char* colors[6] = {
"Red",
"White",
"Blue",
"Yellow",
       "Gold"
};
public:
Scandinavian_flag(int a,int b,int c=-1)
{
flag_color[0]=a;
flag_color[1]=b;
flag_color[2]=c;
}
void print_flag_colors()
{
int i=0;
cout<<"Flag_Colors are: ";
for(i=0;i<3;i++)
{
if(flag_color[i]!=-1)
{
cout<<"Color "<<i+1<<" is "<<colors[flag_color[i]]<<" ";
}
}
}
};

int main()
{
enum Color {
Red = 0, // although it will also be 0 if you don't write this
White, // this will be 1
Blue,
Yellow,
       Gold
};
Scandinavian_flag Denmark{Red,White};
Scandinavian_flag Finland{Blue,White};
Scandinavian_flag Sweden{Blue,Yellow,Gold};
cout<<"Denmark ";
Denmark.print_flag_colors();
cout<<"Finland ";
Finland.print_flag_colors();
cout<<"Sweden ";
Sweden.print_flag_colors();
return 0;
}

Note: try and catch section given in the question could be added to the code.
