Swapping Two Numbers Using Third Variable

  1. Assign var1 value to a temp variable: temp = var1.
  2. Assign var2 value to var1: var1 = var2.
  3. Assign temp value to var2: var2 = temp.

How do you swap two numbers with 2 variables?

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 do you swap two numbers without using a third variable?
