C++ call assembly

1. C++ code embedded assembly

To embed assembly code in C++, you can use the keyword __asm{}. E.g:

#include<iostream>

void math(int a, int &b)
{
	int ans = a;

	__asm
	{
		mov ans,4
	}

	b = ans;
}

void main()
{
	int a = 2;
	int b;
	math(a, b);
	std::cout << b;
}

The output result is:

2. The cpp file calls the asm file
