Python Coding Challange - Question With Answer

 

a = 5
b = -a
c = ~a
print(a, b, c)

What will the values of a, b, and c be after executing the code?

(a) a = 5, b = -5, c = -6

(b) a = 5, b = -5, c = 4

(c) a = 5, b = 5, c = -6

(d) a = 5, b = -5, c = 6

Step-by-Step Explanation:

1. Variable a:

   • a = 5:
   • a is assigned the integer value 5.

2. Variable b:

   • b = -a:
The - (unary minus) operator negates the value of a.
     • Ifa = 5, then b = -5.

3. Variable c:

   • c = ~a:   
                          
             The ~ (bitwise NOT) operator inverts all the bits of the number in its binary                           representation.

     • In binary, 5 is represented as 00000000 00000000 00000000 00000101 (32-bit signed integer).
     • The ~ operator flips all bits:
       11111111 11111111 11111111 11111010.
     • This is a two's complement representation of -6.

     So, ~5 = -(5 + 1) = -6.

4. Output: The print statement outputs the values of a, b, and c:
   
   print(a, b, c)
   
   Result:
   
   5 -5 -6
