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).
If it's a pointer to a float on a machine that represents floating-point numbers in a single word, then it increments by 1, but on a modern byte-oriented machine it might increment it by 8. The point is, the compiler knows the size of the items and the machine's word-alignment requirements, and increments by the correct amount so the sense of ...
In mathematics, a unary operation is an operation with only one operand, i.e. a single input. [1] This is in contrast to binary operations, which use two operands. [2] An example is any function : , where A is a set; the function is a unary operation on A.
Depending on the language, an explicit assignment sign may be used in place of the equal sign (and some languages require the word int even in the numerical case). An optional step-value (an increment or decrement ≠ 1) may also be included, although the exact syntaxes used for this differ a bit more between the languages.
Though Go with Japanese ko rule is EXPTIME-complete, both the lower and the upper bounds of Robson’s EXPTIME-completeness proof [3] break when the superko rule is added. It is known that it is at least PSPACE-hard, since the proof in [2] of the PSPACE-hardness of Go does not rely on the ko rule, or lack of the ko rule. It is also known that ...

What Is A Celery Rib? A celery rib is one of the individual stems that make up the larger bunch of celery, or "stalk." In botanical terms, a rib is a single segment of the plant, and in culinary ...
Similarly, with 3*x++, where though the post-fix ++ is designed to act AFTER the entire expression is evaluated, the precedence table makes it clear that ONLY x gets incremented (and NOT 3*x). In fact, the expression (tmp=x++, 3*tmp) is evaluated with tmp being a temporary value. It is functionally equivalent to something like (tmp=3*x, ++x, tmp).
