Thread: Access specific element in for each loop

Hello

Can you access only a specific element in a for each loop?

For example how would I print only the second element in the Names array?

Code:

#include <windows.h>
#include <array>
#include <iostream>
using namespace std;

int main()
{
    std::array<std::string, 3> Names = {"Harry ", "Dick", "Tom"};

    for (auto& name : Names)
    {
          cout << name << '\n';
    }

     return 0;

}

Like
cout << Names[1] << endl;

If you really need to be subscript aware, then use a subscript
for ( size_t i = 0 ; i < Names.size() ; i++ )

No, Names[1] will access the second letter in each name, returns:
a
i
o

I didnt express myself clear enough, I meant second element of the list.

I would like to access "Dick".

I guess we need to use a subscript for this then.

*shrug*

Code:

#include <array>
#include <iostream>
using namespace std;

int main()
{
    std::array<std::string, 3> Names = {"Harry ", "Dick", "Tom"};

    for (auto& name : Names)
    {
          cout << name << '\n';
    }

    cout << "Names[1]=" << Names[1] << endl;

    return 0;
}

$ g++ foo.cpp
$ ./a.out 
Harry 
Dick
Tom
Names[1]=Dick

Don't confuse Names[1] with name[1]

Ah, of course, thanks!
