Question
What will be the output of the following program on execution?a=0b=5x=(a&b)|(a&a)|(a|b)print("x")150None of the above
Solution 1
The output of the program will be 5. Here's why:
The program is written in Python and uses bitwise operators.
-
a & bis a bitwise AND operation. It will compare the binary representation of a and b. Since a is 0, the result will be 0 because anything AND 0 is 0. -
a & ais also a bitwise AND operation. Since both values are 0, the result will be 0. -
a | bis a bitwise OR operation. It will compare the binary representation of a and b. Since a is 0 and b is 5, the result will be 5 because 0 OR anything is that number. -
The final operation is
x = (a & b) | (a & a) | (a | b). Substituting the results from the previous steps, we getx = 0 | 0 | 5, which equals 5.
So, the print statement will output 5.
Solution 2
The output of the program will be 5. Here's why:
- The program first initializes two variables,
aandb, with the values 0 and 5 respectively. - It then calculates the value of
xusing bitwise operations onaandb. - The
&operator performs a bitwise AND operation. Fora & b, sinceais 0 andbis 5, the result is 0 because the binary representation of 5 (101) AND 0 is 0. - The
|operator performs a bitwise OR operation. Fora | b, sinceais 0 andbis 5, the result is 5 because the binary representation of 5 (101) OR 0 is 5 (101). - The final value of
xis the result of(a & b) | (a & a) | (a | b), which is0 | 0 | 5, which equals 5. - The program then prints the value of
x, which is 5. So, the output of the program is 5.
