C++ syntaxis and diference in code

Question

I trying to "fix" one problem in one game, there is .cpp file, and two version, maybe i found bag. What diference beetwen this 2 examples of code:

Example #1

    // not supposed to do anything while evocate
    if (m_creature->HasAura(SPELL_EVOCATION))
    {
        return;
    }

Example #2

// not supposed to do anything while evocate
if (m_creature->HasAura(SPELL_EVOCATION))
    return;

Maybe it`s stupid question, i am not C++ developer, just knew only python and i am newbie . So what the diference in logic of this code? Thanks alot.

Avoid "debugging" a program in a programming language you don't know (like C++ is for you). And C++ is a very complex programming language. — Basile Starynkevitch, Dec 24 '16 at 14:40

No difference. They are equivalent. When there is only one statement in the body of the if then you can omit the braces.

There is no diffrence in running the code you will get the same resaults. but your second problem in the comments is not really specific. You can make a second question with specific info about what is your problem or you can google your bug. edit: I didnt really understand the question but if you are looking for diffrences between the two version of code. In the first version you addet:

struct boss_curator : public CreatureScript
{
    boss_curator() : CreatureScript("boss_curator") {}

thank you! its specific problem in game. boss must stop do anything and cast spell "Evocation" - in "chaneling mode" (dont break it), but he do it (break spell cast) many times and start again and again, and after each stopt\start he summon new mobs. There is 2 version of this code , i use "new" version https://github.com/mangos/ScriptDev3/blob/master/scripts/eastern_kingdoms/karazhan/boss_curator.cpp - but exist older https://github.com/scriptdev2/scriptdev2/blob/master/scripts/eastern_kingdoms/karazhan/boss_curator.cpp i trying compare it – Aqia Ru Dec 24 '16 at 14:53
