do {…} while(false)

Question

I was looking at some code by an individual and noticed he seems to have a pattern in his functions:

 function()
{
 

        

Answer 1

The break as goto is probably the answer, but I will put forward one other idea.

Maybe he wanted to have a locally defined variables and used this construct to get a new scope.

Remember while recent C++ allows for {...} anywhere, this was not always the case.
