$ uname -a
CYGWIN_NT-6.1 idefix 1.7.29(0.272/5/3) 2014-04-07 13:46 x86_64 Cygwin
I do not understand the output of this small program usinf the <vector>
container.
#include <iostream>
#include <vector>
using namespace std;
int main() {
cout << "!!!Hello World!!!" << endl;
int i = 1;
int j = 2;
int k = 3;
vector<int*> v(5);
v.push_back(&i);
v.push_back(&j);
v.push_back(&k);
for( auto &n : v) {
cout << "int* =" << n;
if (n != 0)
cout << ", int=" << *n;
cout << endl;
}
return 0;
}
!!!Hello World!!!
int* =0
int* =0
int* =0
int* =0
int* =0
int* =0x22aa60, int=1
int* =0x22aa5c, int=2
int* =0x22aa58, int=3
Is this could be a bug?
