Nested Functions in C++

Nested Functions in C++
Although C++ does not allow nested function declaration, you can simulate it using a structure with a static function:


void outer()
{
static int v1 = 5;
int v2 = 5;

struct thru
{
static void inner()
{
std::cout <<>

The inner() function will not have access to local variables of outer() (the line that is commented out in the code above will cause an error, for example); however, it will be able to access the local static variable v1 in outer().
