Can we use XOR operator to swap two numbers?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).

How can we swap two numbers without using any other variable?

Program to swap two numbers without using the third variable

1. STEP 1: START.
2. STEP 2: ENTER x, y.
3. STEP 3: PRINT x, y.
4. STEP 4: x = x + y.
5. STEP 5: y= x – y.
6. STEP 6: x =x – y.
7. STEP 7: PRINT x, y.
8. STEP 8: END.

How can we swap two numbers without third variable using bitwise operators?

Bitwise operators can also be used to swap two numbers without using a third variable. XOR bitwise operator returns zero if both operands are the same i.e. either 0 or 1 and return 1 if both operands are different e.g. one operand is zero and the other is one.

Which of the following Bitwise Operators can be used efficiently to swap two numbers?

Logic to swap two numbers using bitwise operator We can use bitwise XOR ^ operator to swap to numbers.

Why XOR is used for swapping?

In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required.

How do you swap two numbers?

Let’s see another example to swap two numbers using * and /.

1. #include
2. #include
3. int main()
4. {
5. int a=10, b=20;
6. printf(“Before swap a=\%d b=\%d”,a,b);
7. a=a*b;//a=200 (10*20)
8. b=a/b;//b=10 (200/20)

What is the bitwise XOR operator?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).

How to swap two variables using XOR operator?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number which has all the bits as 1 wherever bits of x and y differ.

How to swap two numbers using bitwise operator?

Java Program to Swap Two Numbers Using Bitwise Operator In Java, there are many ways to swap two numbers. Generally, we use either swap () method of the Math class or use a third (temporary) variable to swap two numbers. Except these two ways, we can also swap two numbers using the bitwise operator (XOR) and using division and multiplication.

Which operator is used to swap two numbers?

Bitwise Operator: Bitwise XOR operator is used to swap two numbers. It is represented by the symbol (^). It compares bits of two operands and returns false or 0 if they are equal and returns true or 1 if they are not equal.
