Thread: A switch question

>>try reducing the string to an integer using a map

IMO that would just complicate things even more, and I don't know if it would be very efficient either. I think it's just as simple to do:

Code:

#include <iostream>

#define STR1 "String1"
#define STR2 "String2"
int main()
{
  std::string test;
  std::cin>>test;
  if (test==STR1)
    //do something
  else if (test==STR2)
    //do something else

}

That's not too hard to read is it?

but what if you have a LOT OF STRINGS@#%

huh, your not considering the full impliciations and possibliities of each situation
huh

huh, if he doesn't know that you can't switch a string do you think that he really needs to learn use a map for alot of strings
huh

yes
syntax is secondary to programming

i don't even invoke a compiler anymore, i just imagine my creations running perfectly

#define STR1 "String1"
#define STR2 "String2"

Might want to make that:

const std::string str1("String1");
const std::string str2("String2");

Just for the sake of not mixing C and C++ strings

I suppose so...Although I like to use defines so I can declare them in a header file to keep things a bit neater.

Couldn't you just create a singleton to encapsulate all the messy global variables, then declare the const strings in that?

**EDIT**
Actually, couldn't you just do this:

Code:

#define STRING1 std::string("String1")

Heh, not much to look at I guess...

I don't know, never used singleton for anything before.

>>Actually, couldn't you just do this:

I suppose so, but that would create a new string everything you used it. It seems kind of like an abuse of defines though, after all, the string class does have a comparison operator for cstrings, so why not use it?

Why would you, when you can have so much fun with confusing #define's that construct new objects of classes every time you use them?
