Windows 64-bit assembly in C++

[iQChange]

I saw an tutorial that teaches asm in C++. I saw in the video this code:

#include <iostream>
int GetASM()
{
    asm("mov %eax,1000");
}
int main()
{
    std::cout << GetASM();
}

But, when compiling and runing, my program instantly crashes. What am I doing wrong?

[Cubbi]

the meaning of the asm keyword http://en.cppreference.com/w/cpp/language/asm is different in every compiler - see links at the bottom of that page for some common ones,

its equivalent to return 1000 in terms of C++

[iQChange]

I know, but the program instantly crashes.

What compiler are you using? What compiler is the tutorial using? Are they the same?

[iQChange]

@LB Nope. I use GNU GCC (MinGW), and the tutorial uses MSVC++, but I saw that using the GCC asm() and string literals results in the same. At least, should. Do you think that my asm code is correct?

[LB]

No, Microsoft's inline assembly is completely different from GNU's inline assembly.

Can you help me? I'm just a assembly begginer. Do you haz teh codez? :P

In AT&T syntax it would be: asm("mov $1000, %eax");
Try it and tell us if it doesn't explode your computer.

Haha, funny (ironic).
