foreach VS 2010 macro

[Rick]

wow, nevermind.

[Canardia]

It's a Boost command.

[Rick]

It seems VS already has this. I wasn't aware as I never used it and never looked into it before.

[Canardia]

Yeah, Boost is nowadays industrial standard too, so you will find it in many compilers by default, just like STL.

[Rick]

Are you sure it's the actual boost library in VS 2010? If I google VS 2010 and boost it seems people are still trying to build boost for it. Why would one have to do that if it was already in there?

[TylerH]

Boost has about 50 or so libraries that do different things.

[Rick]

Yeah, I was just questioning if VS actually used boost or not.

[Roland]

for_each is a normal STL function.

No BOOST needed

Works in VS2008 and VS2010

 

Example:

 

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;


class myTest
{
public:
void operator() (const std::string& s ) 
{
	cout << " " << s.c_str() << endl ;
}
} ;

int main()
{
myTest test;

vector<string> myStrings ;
myStrings.push_back("For" );
myStrings.push_back("Each" );
myStrings.push_back("Works" );

for_each( myStrings.begin(), myStrings.end(), test );


return 0;
}

[Rick]

Yeah, but VS 2005 and above has what I would consider a "normal" foreach. One that doesn't require a function. One that is inline. I didn't know that before.
