what does + sign after variable mean?
c, c++
Solution
I think DrYap has it right.
x = + + a + + + a + + + 5;
is the same as:
x = + (+ a) + (+ (+ a)) + (+ (+ 5));
The key points here are:
1) c, c++ don't have + as a postfix operator, so we know we have to interpret it as a prefix
2) monadic + binds more tightly (is higher precedence) than dyadic +
Funny isn't it ? If these were - signs it wouldn't look so strange. Monadic +/- is just a leading sign, or to put it another way, "+x" is the same as "0+x".
Problem
what will be the output of following code `int x,a=3; x=+ +a+ + +a+ + +5; printf("%d %d",x,a);` ouput is: 11 3. I want to know how? and what does + sign after a means?
