Q

are used to assign values to variables in programming language

A

Assignment operators

32
Q

is used to assign a value to a variable.

A

The basic assignment operator (=)

33
Q

): It multiplies the variable on the left-hand side by the value on the right-hand side and assigns the result to the left-hand side variable.

A

Multiplication Assignment Operator (*=

34
Q

It divides the variable on the left-hand side by the value on the right-hand side and assigns the result to the left-hand side variable

A

Division Assignment Operator (/=):

35
Q

It performs floor division on the variable on the left-hand side by the value on the right-hand side and assigns the integer quotient to the left-hand side variable.

A

Floor Division Assignment Operator (//=):

36
Q

It computes the remainder when the variable on the left-hand side is divided by the value on the right-hand side and assigns the result to the left-hand side variable

A

Modulus Assignment Operator (%=):

37
Q

are used to manipulate individual bits of binary numbers in computer programming.

A

Bitwise operators

38
Q

The AND operator compares two bits and returns 1 if both bits are 1, otherwise returns 0

A

AND Operator (&):

39
Q

The OR operator compares two bits and returns 1 if at least one of the bits is 1, otherwise returns 0.

A

OR Operator (|):

40
Q

The XOR operator compares two bits and returns 1 if the bits are different (one 0 and the other 1), otherwise returns 0.

A

XOR Operator (^):

41
Q

The complement operator flips the bits, turning 0 to 1 and 1 to 0.

A

Complement Operator (~):

42
Q

The left shift operator shifts the bits of a number to the left by a specified number of positions, effectively multiplying the number by a power of 2.

A

Left Shift Operator («):

43
Q

The right shift operator shifts the bits of a number to the right by a specified number of positions, effectively dividing the number by a power of 2.

A

Right Shift Operator (»):
