Switch statement with returns — code correctness

Question

Let\'s say I have code in C with approximately this structure:

switch (something)
{
    case 0:
      return \"blah\";
      break;

    case 1:
    case 4:
         


        

Answer 1

For "correctness", single entry, single exit blocks are a good idea. At least they were when I did my computer science degree. So I would probably declare a variable, assign to it in the switch and return once at the end of the function
