Accessing variables with different scope in C++
- by Portablejim
With
#include <iostream>
using namespace std;
int a = 1;
int main()
{
int a = 2;
if(true)
{
int a = 3;
cout << a
<< " " << ::a // Can I access a = 2 here?
<< " " << ::a << endl;
}
cout << a << " " << ::a << endl;
}
having the output
3 1 1
2 1
Is there a way to access the 'a' equal to 2 inside the if statement where there is the 'a' equal to 3, with the output
3 2 1
2 1
Note: I know this should not be done (and the code should not get to the point where I need to ask). This question is more "can it be done".
