On another SE site I saw code similar to this:

int x[] = {1,2,3,4};
....
x[0] = {99};

For the assignment, is there an advantage to this over simply:

x[0] = 99;

  • I think this might prevent implicit narrowing conversions, but for an int literal it's going to be absolutely irrelevant. – amon Jun 15 '17 at 12:32

Yes, there is one.

Those brackets disable implicit narrowing conversions, so if the type of the expression inside does not fit an int it's an error instead of a silent loss of data.
Of course, 99 is plenty small and thus of type int.

Try it with a sufficiently large literal like 99999999999: http://ideone.com/D89wVx
