Tags bitwise bitwise operators

In one of my training sessions, some people complained that the precedence of operators was too difficult to remember.

One student recommends using a sentence to help the memory:

"Ulcer addicts really like C A lot", that is "ulcer patients are particularly fond of (vitamin) C".



Mnemonic words

Operator type

Operator

Ulcer

Unary

+-++–[[Rest ...]

Addicts

Arithmetic (and shift)

*/% +-<< >>

Really

Relational

> < >= <= = =!=

Like

Logical (and bitwise)

&& | | & | ^

C

Conditional (Ternary)

A > B? X:y

A Lot

Assignment

= (and compound assignment like *=)


Of course, the table above is not a perfect mnemonic for shift and bitwise operators, but it does work for other operations.
