Lets see the X-OR operation of 4 and 5. The binary format of 4 is 100 The binary format of 5 is 101 ------- 001 ------- Answer after performing bitwise X-OR is 1 and that is stored in the variable a. Next, in the line b = a ^ b, the value 1 is X-ORed with 5 and the result is stored in the variable b. Lets the X-OR operation of 1 and 5. The binary format of 1 is 001 The binary format of 5 is 101 ------- 100 ------- Answer after performing bitwise X-OR is 4 and that is stored in the variable b. Next, in the line a = a ^ b, the value 1 is X-O Red with 4 and the result is stored in the variable a. Lets the X-OR operation of 1 and 4. The binary format of 1 is 001 The binary format of 4 is 100 ------ 101 --- Answer after performing bitwise X-OR is 5 and that is stored in the variable a. Thus both the values got swapped using X-OR operator. ================================================================ What is Arithmetic overflow? Method 1 & 2 may cause an arithmetic overflow when the values of a & b are significantly large and here is what we mean by it. Arithmetic overflow occurs when the result of an arithmetic operation is a value that is too large to fit in the available storage space. Consider 3 four-bit variables a, b, c. The value stored in the variables a and b is 15 and 1 respectively. We need to add the two variables and store the result in the variable c. 15 in Binary 1111 1 in Binary 0001 --------------------------------- c = 10000 --------------------------------- After adding, the result is 16, we get a 5 bit variable and this is too large to fit in 4-bit variable c. That is how arithmetic overflow occurs. ====================================================================== In this article, we will be discussing the program to swap two numbers without using third variable in C, C++, Java. There are 5 methods to do swap two numbers without using a temporary variable.
