print pattern (0011+0101 +1001+0110+ 1010+1100)* + 11 + 00

---

something wrong in loop condition.

ignore the question. It may lead to infinite loop too.

if P1 : while(lock==0); and P2 : while(lock==1);

then option B correct.

 

if P1 : while(lock!=0); and P2 : while(lock!=1);

 

then option C correct.

---

why given conditions are wrong? @Shaik?

---

both are same condition, rt ?

equal to 0 or not equal to 1 means same for the variable which have the value either 1 or 0.

---

Answer given is option a

---

let the question is right, you entered in any process and printed something. then lock can be modified into 0. then while loop leads to infinite loop. in that case how Option A is right ?

---

The only characters ever printed are $0$ and $1$ so such string will always belong to $(0+1)^*$ ..?

---

surely NO.

Discussing a Non-standard question for matching the answer is waste :(
