Array increment operator in C

Part-1: Array names are constant (not modifiable lvalue), your can add value to array name but can’t modify it. Expression a + 2 doesn’t modify a itself but when you do a++ that is equivalent to a = a + 1 try to modify array name –lvalue error. The expression a++ in second printf is … Read more

Pre increment vs Post increment in array

You hit the nail on the head. Your understanding is correct. The difference between pre and post increment expressions is just like it sounds. Pre-incrementation means the variable is incremented before the expression is set or evaluated. Post-incrementation means the expression is set or evaluated, and then the variable is altered. It’s easy to think … Read more

Incrementor logic

Quoting Java Language Specification, 15.7 Evaluation Order: The Java programming language guarantees that the operands of operators appear to be evaluated in a specific evaluation order, namely, from left to right. The left-hand operand of a binary operator appears to be fully evaluated before any part of the right-hand operand is evaluated. If the operator … Read more

Order of operations for pre-increment and post-increment in a function argument? [duplicate]

Well, there are two things to consider with your example code: The order of evaluation of function arguments is unspecified, so whether ++a or a++ is evaluated first is implementation-dependent. Modifying the value of a more than once without a sequence point in between the modifications results in undefined behavior. So, the results of your … Read more

post increment operator java

Let’s break down your own argument: According to the author, j=j++; is similar to temp=j; j=j+1; // increment j=temp; // then assign Yes, you’re right so far…, but here’s where you got it wrong: But a=b++; makes b=1. So it should’ve evaluated like this, a=b; // assign b=b+1; // then increment WRONG! You’re not applying … Read more
