    another question on assembly.
    i'm having problems with inline assembly.
    assignment.cpp(27) : error C2443: operand size conflict
    assignment.cpp(28) : error C2443: operand size conflict
    assignment.cpp(29) : error C2443: operand size conflict
    my code is the following
    Code:
    #include<iostream>
    using namespace std;
     
    int sum(int a,int b);
     
    int main()
    {
    	int a=0,b=0,num=0;
     
    	cout<<"enter integer";
    	cin>>a;
    	cout<<"enter integer";
    	cin>>b;
    	num = sum(a,b);
    	cout << num;
     
    	return 1;
    }
     
    int sum(int a, int b)
    {
    	int n=0;
     
    //it doesn't like my inline block here
    //i'm assuming it means that the integers a, b, n differ in size from the ah register. 
    //how would i fix this? cast?
    	_asm
       {
    			mov ah, a 
    			add ah, b
    			mov n, ah
       }
     
    	return n;
    }
    So, I figured it out. I used short instead of int, and it worked.
