[*] 21

Given the following function, which one of the following claims is incorrect? (i.e., find the FALSE statement)
    int CrazyFun(int & in) { return ++in * 10; }
#side-effects
* If x is 0 and I call `CrazyFun(x)` it will return 10
* If x is 0 and I call `CrazyFun(x)`, x will then be 1
[*] If x is 10 and I call `CrazyFun(x)` it will return 100
* if x is 5 and I call `CrazyFun(x)`, x will then be 6
