Comments

ans is C

---

why compiler error??is there any flaw in this code..u can check and verify with some online compiler

---

on techtud they mention error in this line

k=(i+j)++;

my ans was also 11

---

The error is L - value error ,I.e

It is definitely wrong to write (i+j) = (i+j) +1.

This error comes under compiler error .

---

can you explain what is L value error

---

thanks @kapil for clarification

---

but why @kapul when i run on code block GCC compiler even it is not giving any worning message and print 11 successfully?

---

Where have you written (i+j)++ ?

---

ohh, thank anyway..

---

(i+j) is an intermediate constant value, can't be incremented. So (i+j) is basically a r-value.

Answer 2

i+j=11and it is executing in the way 11++ which is compilation error.

Answer 3

compile error as lvalue required for post increment
