Dunno which is should be, but the 'c' language doesn't allow unary '+' in front of numerical literals... so I followed that lead.
I don't know which C language you are talking about. Try compiling
the following program with options -ansi -pedantic-errors:#if + +1 int main (void) { int foo[+ +1] = { + + + + + + + + + + +1 }; return foo[0]; } #endif
This demonstrates that unary + works in front of numerical literal,
both in the main language and in the preprocessor. I don't know of
a way to test whether the last + before the 1 is actually
considered part of the literal or not. However, both scanf() and
strtod() consider + as part of a float literal (was there ever a
time that they didn't? really?).
What would be the advantages/disadvantages of either way? My
intuition says that +1 should be a symbol, perhaps because it is
rare to write positive numbers in math with a leading +.
Maybe the errant newbie might be confused when +1 turns out to be a
symbol. But if Pd starts removed + signs upon save, then that could
also be annoying.
