  • Behaviour of increment and decrement operators in Python
    Python does not have unary increment decrement operators (-- ++) Instead, to increment a value, use a += 1 More detail and gotchas But be careful here If you're coming from C, even this is different in python Python doesn't have "variables" in the sense that C does, instead python uses names and objects, and in python ints are immutable
  • Decrement in Java - Stack Overflow
    You are using the post-decrement operator This is because you are writing result--but not --result The value of the expression result--is a copy of result, it is defined before the decrementing That's why it's called post-decrement After the value of the expression result--is defined, result is decremented
  • oop - Java Increment Decrement Operators - Stack Overflow
    These are called Pre and Post Increment Decrement Operators x++; is the same as x = x + 1; x--; is the same as x = x - 1; Putting the operator before the variable ++x; means, first increment x by 1, and then use this new value of x
  • How does the decrement operator work in a while statement?
    It is using a post decrement so x is modified after returning it's current value so it is really equivalent to this: while( ( x - 1) ) and the loop will run until the expression is false or in the this case 0 which is equivalent to false So the run goes like this:
  • Decrement value in mysql but not negative - Stack Overflow
    I want to decrement a value when user delete it in php and mysql I want to check not to go below than 0 If value is 0 then do not decrement mysql_query("UPDATE table SET field = field - 1 WHERE
  • Which loop has better performance? Increment or decrement?
    Decrement loops down to zero can sometimes be faster if testing against zero is optimised in hardware But it's a micro-optimisation, and you should profile to see whether it's really worth doing The compiler will often make the optimisation for you, and given that the decrement loop is arguably a worse expression of intent, you're often
