Question

Given the values of A=3, B=4 and C=5, what is the final value of variable C when C=B++; B=A; B=--C?

Answer 1

Answer:

finally c = 3

Explanation:

initially

a = 3

b = 4

c = 5

c = b++ (post increment)

hence c = 4

b = 5;

b = a => b = 3;

b = --c(pre decrement)

b = 3 and c = 3

Answer 2

A = 3 , B=4 , C=5

The statements that are executed are:

1) C= B++;

As this is post increment, so the updated value is stored in B but not returned to C, so the value of B is returned to C.

So, C=4 , B=5, A=3

2) B=A;

Now, B=3, A =3, C=4.

3) B= --C;

As it is pre decrement, so the updated value of C is returned to the variable C as well as to B.

Now, B= 3 , C=3, A=3. (Final values)

So, the final values of C is 3.
