Using Labels with the goto Statement

The appearance of an identifier label in the source program declares a label. Only a goto statement can transfer control to an identifier label. The following code fragment illustrates use of the goto statement and an identifier label:

A label cannot appear by itself but must always be attached to a statement. If a label is needed by itself, place a null statement after the label.

The label has function scope and cannot be redeclared within the function. However, the same name can be used as a label in different functions.

// labels_with_goto.cpp
// compile with: /EHsc
#include <iostream>
int main() {
   using namespace std;
   goto Test2;

   cout << "testing" << endl;

   Test2:
      cerr << "At Test2 label." << endl;
}
At Test2 label.
