Re: another copy constructor question

I was wondering why in the following piece of code, the function test1
calls a copy constructor at return and why test2 does not. Is the usage
of multiple return statements in one function not really a good
programming style?
Thanks for the help
#include <iostream>
class foo {
public:
  foo() { };
  foo(const foo &c) { std::cout << "copu" << std::endl; }
};
foo test1() {
  if (true) {
    foo c;
    return c;
  }
  return foo();
}
foo test2() {
  foo c;
  if (true) {
  }
  return c;
}
int main(void) {
  std::cout << "test 1" << std::endl;
  test1();
  std::cout << "test 2" << std::endl;
  test2();
  return 0;
}
