Exercise caution when using the increment/Decrement Operators (C ++) and Decrement Operators
Incrementing ++ and decimal operators-both seemingly and in use, they all feel simple and elegant, but there are uncontrollable traps in them, we must be
Interlocked. increment method: Make ++ an atomic operation; interlocked. decrement method makes -- an atomic operation.What is an atomic operation. That is, it will not be interrupted by others, because a statement in C # will become multiple
In C and C + +, the self-increment (+ +) and decrement (-) operators are often used in expressions to increase the value of a variable by 1 or minus 1, for example:++i (before using I, the value of I is added 1, if the original value of I is 3,
