OR simplified one

 

# include<reg51.h>

void main(void)

{

unsigned char x,y,z, a,b,c; //define variables

 x=0x12; //first 8-bit number

y=0x34; //second 8-bit number

P0=0x00; //declare port 0 as output port

P1=0x00; //declare port 1 as output port

P2=0x00; //declare port 2 as output port

P3=0x00; //declare port 3 as output port

z=x+y; // perform addition

P0=z; //display result of addition on port 0

a=y-x//perform subtraction

P1=a// display result of subtraction on port 1

b=x*y// perform multiplication

P2=b//display result of multiplication on port 2

c=y/x//perform division

P3=c // display result of division on port 3

while(1);

}
