What is the purpose of the unary plus (+) operator in C?

Question

In C, it\'s legal to write something like:

int foo = +4;

However, as far as I can tell, the unary plus (+) in +4

Answer 1

Pretty much. It's mainly present for completeness, and to make constructions like this look a little cleaner:

int arr[] = {
    +4,
    -1,
    +1,
    -4,
};
