In C#, is there a difference between the code (all in one statement, not part of a larger one) arr[0]++; and ++arr[0];
I recently read: \"The e开发者_开发百科xpressions (++i) and (i++) have values and side effects.
This question already has answers here: Why are these constructs using pre and post-increment undefined behavior?
I can\'t make heads or tails of the following code from \"java puzzlers\" by joshua bloch. public class Test22{
I have never seen the usecase for pre-increment and post-increment in actual code. The only place i see them most often are puzzles.
If I have for example a class with instance method and variables class Foo { ... int x; int bar() { return x++; }
Why does this code always produce x=2? unsigned int x = 0; x++ || x++ || x++ || x++ || ........; printf(\"开发者_JAVA百科%d\\n\",x);
Why does this int x = 2; for (int y =2; y>0;y--){ System.out.println(x + \" \"+ y + \" \"); x++; } prints the same as this?
