C/C++ conditional return statements [duplicate]

Answer 1

Multiple return statements is perfectly valid in C/C++. But make sure that at least one of the return statements is always executed. The following function is incorrect,

int foo(int x)
{
  if(x>0)
  {
    return 1;
  }
  else if(x==0)
  {
    return 0;
  }
  else
  {
    // No return in this block
  }
}

such situations should be avoided in C/C++.
