LAB DESCRIPTION:

This second lab, we were asked to write a program this different operations, such as addition, subtraction, multiplication and exponential. For this program, I used the ” if….then”, and “else if….then” conditions to be able set up this cases. this is lab, the idea to how to set the program was there. but the set up of the writing was a little tough. I might say. Also I had a program that I couldn’t figure out because the compiler was running the program. The problem was I was missing the double equal sign in the set up of the condition: (if (ecx”==”1) then:). The professor saw it and everything ran perfectly.

Code:

Program Operation;
#include("stdlib.hhf");
Static
a: int32;
x: int32;
y: int32;
z: int32;
i: int32;
j: int32;
begin Operation;

stdout.put( " choose operation ",nl);
stdout.put( "1 = addition",nl);
stdout.put( "2 = substraction",nl);
stdout.put( "3 = multiplication",nl);
stdout.put("4 = exponantial",nl);
stdout.put( "enter option ",nl);
stdin.get(a);
mov(a,ecx);

if (ecx==1) then;

	  stdout.put( "enter x ",nl);
	  stdin.get(x);
	  stdout.put( "enter y ",nl);
	  stdin.get(y);
	  mov(x,eax);
	  mov(y,ebx);
	  add(eax,ebx);
	  mov(ebx,z);
	  stdout.put(z);

elseif(ecx==2) then
	  stdout.put( "enter x ",nl);
	  stdin.get(x);
	  stdout.put( "enter y ",nl);
	  stdin.get(y);
	  mov(x,eax);
	  mov(y,ebx);
	  sub(ebx,eax);
	  mov(eax,z);
	  stdout.put(z);

elseif (ecx==3) then
	  stdout.put( "enter x ",nl);
	  stdin.get(x);
	  stdout.put( "enter y ",nl);
	  stdin.get(y);
	  mov(x,eax);
	  mov(y,ebx);
	  mul(ebx);
	  mov(eax,z);
	  stdout.put(z);

elseif (ecx==4) then 
stdout.put(nl);
stdout.put( "enter x ",nl);
	  stdin.get(x);
	  stdout.put( "enter y ",nl);
	  stdin.get(y);
	mov(x,eax);
		mov(y,ebx);
		mov(1,z);
			for(mov(0,i); i<ebx; inc(i)) do
 				mov(0,ecx);
			for(mov(0,j); j<eax; inc(j)) do   			
				add(z,ecx);             		
		endfor; 		  
 			mov(ecx,z); 			
		endfor; 		

                stdout.put("the answer is: ",z,nl); 
		endif;
		stdout.put(nl);

 end Operation;
