4) 0-address machines

Solution:
Let B+C = M
And D+E = N
Writing code to implement the given expression i.e. A = (B+C) * (D + E)

3-Address 0-Address
add M,B,C
add N,D,E
mul A,M,N
2-Address
load M,B
add M,C
load N,D
add N,E
mul N,M
store A,M
1-Address
lda B
adda C
sta M

adda E
sta N
mula M
sta A
0-Address
push B
push C
add
push D
push E
add
mul
pop A
