Question

x = c++ – ++b * ++c;
please tell me the answer fast
​

Answer 1

Answer: x = -12

Solution:

Given, b = 2, c = 3

Expression:

x = c++ - ++b * ++c

Evaluation:

x = 3 - 3 * 5

x = 3 - 15

x = -12

Explanation:

The above operators used are all increment operators that work in a way where they increase the value of the variable by 1, depending upon the position of ++ (either before of after the variable).

Prefix Form : ++x

It increments the variables expression then uses the new value in the expression.

Trick to remember - Pehle istemaal krein fir vishwas krein

(Meaning: first increase the value then use it right there)

Postfix Form : x++

The variables value is first used in the expression and then it is incremented after the operation.

Trick to remember - Pehle vishwas krein fir istemaal krein

(Meaning: increase the value but do not use it right there, use it in the next term)

Answer 2

Answer:

x = 9

Explanation:

find x if b = 2 and c = 3

x = c++ - ++b * ++c;

x = 3 - 3 x 4 (c++ = 3, ++b = 3 and ++c = 4)

x = 3 - 12

x = 9
