I'm trying to write a class that will read and organize the command line arguments of a program.
Like, it will read -a as a 'switch', and --abcd as a 'switch' and you can define different switches as having parameters, so -a bc de fg will have bc and de as its parameters (that MUST go after -a if -a is defined as having two parameters) and fg would (if -a was only defined as having two parameters) be a standalone "statement"... anyway,
is it possible to overload the [] brackets in a class?
Say if -a had two switches, and there was an object aswitch for that switch...
cout<< aswitch; would output true if -a was set, false if otherwise,
cout<< aswitch[0]; would output the first parameter, and
cout<< aswitch[1]; would output the second.
right now I just have bool aswitch::isSet(); and char* aswitch::params(int);
Also, I don't know if i have the right understanding of "friend" functions...
class className{
public:
friend int funcName();
protected:
static char* varName;
};
int funcName(){
className varName = "newValue";
return 0;
}making a "friend" function gives just a normal function outside a class access to that class's protected members right? Did I use it correctly in this example?
