Reputation: 482 | 7 |  C/C++ prioroty question
Am confused.. int m[2] = { 1, 5 }; cout << ++*m; //this gives 2 my question is, why is the dereference operator evaluated before ++ inspite of the fact that ++ has a higher precedence than *?  ANy pointers there? |

Операторы ++ и * имеют одинаковый приоритет и порядок выполнения справа налево. Скобки тебе не помогут?

Everything seems to be fine... I don't see any problem here. To be simple... in case of prefix unary operators, the operators are executed in the right-to-left order... |

operator ++(void) has to be applied to something. Something is dereferenced m.
