Which one of the following codes is faster in excecution?

Question

Basically which one of the Codes will return 0, faster ?

// if the answer is "the same" because the code is simple than imagine a more complex code variant written in the same way but with more code.

Code 1:

int a = 0;

if(a == 1){ 
    return 1;
}else{
    return 0;
}

Code 2:

int a = 0;

if(a == 1){ 
    return 1;
}
return 0;

Generate (optimized) assembly and look for yourself if there is any difference. — Some programmer dude, Jan 18 '16 at 16:22
They will probably have the same performance, no matter how simple or complex the code is. That's because both snippets are equivalent and will likely compile down to the same code. — Theodoros Chatzigiannakis, Jan 18 '16 at 16:22
Assuming the compiler actually generates different code for the two (which it probably won't), the difference will not be measurable. — John Bode, Jan 18 '16 at 16:24
They are basically the same. I don't think there will be a difference — Claudio Cortese, Jan 18 '16 at 16:30

There will be no difference in the compiler generated code. The else is unnecessary but may be written for clarity.
