lets say i have this code...
How would I (can I) access, say, the third nested "i" from the innermost scope. And you can spare me the tongue lashings, Im just being curious, I would never do such a thing.Code:int i; // defined global int main() { int i; { int i; { int i; { int i; { int i; ... }}}} return 0; }
C Code. C Code Run. Run Code Run... Please!

AFAIK you cannot. Stroustrup's book says it: "There is no way to use a hidden local name"
okay

Oh I dont know
Just kidding though....you wouldnt want to do thisCode:/*Assume VC++6*/ int i; // defined global int main() { int i = 1;//block 1 { int i = 2;//block 2 { int i = 3;//block 3 { int i = 4;//block 4 { int i = 5;//block 5 _asm{ push eax lea eax,i add eax, 2 * SIZE i mov eax,dword ptr [EAX] mov i,eax pop eax } std::cout << "Value in block 3 = " << i << std::endl; }}}} return 0; }
Ah, finally I've got a reason to learn asm.

Namespaces could solve the problem, its not nice but possible.How would I (can I) access, say, the third nested "i" from the innermost scope. And you can spare me the tongue lashings, Im just being curious, I would never do such a thing.
But still I prefer Fordy´s approachCode:#include <iostream> namespace foo { int i = 5; namespace foo2 { int i = 10; namespace foo3 { int i = 20; } } } int main() { std::cout << "First i is " << foo::i << std::endl; std::cout << "Second i is " << foo::foo2::i << std::endl; std::cout << "Third i is " << foo::foo2::foo3::i << std::endl; return 0; }.
I like ripper079's approach, I didn't thik of namespace this way.
Oooh, I wanna learn ASM
Just Google It. √
