The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).
Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C).An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.
The compiler is free to reorder these reads in program order as it sees fit, and there will be no program-visible side effects. What if assigned value is also pointer indirected? *sum = *a + *b + *c; Here the language definition is unlikely to allow the compiler to break this apart as follows:
In C, array indexing is formally defined in terms of pointer arithmetic; that is, the language specification requires that array[i] be equivalent to *(array + i). [8] Thus in C, arrays can be thought of as pointers to consecutive areas of memory (with no gaps), [8] and the syntax for accessing arrays is identical for that which can be used to ...
LOOP is a simple register language that precisely captures the primitive recursive functions. [1] The language is derived from the counter-machine model. Like the counter machines the LOOP language comprises a set of one or more unbounded registers, each of which can hold a single non-negative integer. A few arithmetic instructions (like 'CleaR ...

All the operators (except typeof) listed exist in C++; the column "Included in C", states whether an operator is also present in C. Note that C does not support operator overloading. When not overloaded, for the operators && , || , and , (the comma operator ), there is a sequence point after the evaluation of the first operand.
