Difference between local scope and function scope

Question

Once I assumed that these two have the same meaning but after reading more about it i\'m still not clear about the difference. Doesn\'t the local scope sometimes refer to sc

Answer 1

bool m[3][3];
void f1()
{
  int i;
  // redefining a variable with the same name in the same scope isn't possible
  //int i; //error C2086: 'int i' : redefinition
}

void f2()
{
  int i; // ok, same name as the i in f1(), different function scope.

  {
    int i; // ok, same name as the i above, but different local scope.
  }

  // the scope if the following i is local to the for loop, so it's ok, too.
  for (int i = 0; i < 3; i++)
  {
    for (int j = 0; j < 3; j++)
    {
      if (m[i][j])
        goto loopExit;
    }
  }
loopExit:
  std::cout << "done checking m";
// redefining a label with the same name in the same function isn't possible
// loopExit:; // error C2045: 'loopExit' : label redefined
}

void f3()
{
loopExit:; // ok, same label name as in f2(), but different function scope
}
