Question

Which  label sequence  correctly implements short-circuit evaluation? 
 if ((a < b && c != d) || e == f) 
     x = 1; 
 else 
     x = 0;

Answer

if a < b goto L1 
 if c != d goto L1 
 if e == f goto L1 
 x = 1 
 x = 0

Answer

x = 1 
 if a < b goto L1 
 x = 0 
 L1:

Answer

if a < b goto L1 
 goto L4 
 L1: if c != d goto L2 
 goto L4 
 L2: goto L3 
 L4: if e == f goto L3 
 goto L5 
 L3: x = 1 
 goto L6 
 L5: x = 0 
 L6:

Answer

if a < b goto L1 
 goto L2 
 L1: if c != d goto L3 
 goto L2 
 L3: x = 1 
 goto L4 
 L2: if e == f goto L3 
 x = 0 
 L4:
