main(){ int a=5,b=10; printf("\r\n Before Swap"); printf("\r\na=%d and b=%d",a,b); a^=b^=a^=b; printf("\r\n After Swap"); printf("\r\na=%d and b=%d",a,b); return 0; }

XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).So the code is --------------------------------------- int x = 10, y = 5; x = x ^ y; // x now becomes 15 (1111) y = x ^ y; // y becomes 10 (1010) x = x ^ y; // x becomes 5 (0101)
