I typed this code mistakenly but this compiled and gave a answer. Can you explain how "&&" react in here??

When you do &&, it evaluates to either true or false depending on whether the condition is met. For example, 5&&5 is true while 5 &&6 is false. The boolean value of true or false is then cast to an int implicitly meaning 0 if it is false and 1 if it is true. Therefore 1 is added to 1 most of the time printing out 2 since the majority of the time, rand() will not give out 6.

Then How about this?? In here there's only one "&" symbol.

Yeah, you're right. That's why I get for answering a question when sleep deprived.. To expand more on the bitwise and, you have to consider numbers in binary notation. Binary means everything is either a 0 or a 1. Essentially this means you are using base 2 representation it it makes more clear. The normal decimal system we use is base 10. Ex. is 100 for base 10 notation. 100 is 10^(31). Now for binary notation: Each number means you take 2 to that power or not. I will be showing 8 bits only for simplicity when converting numbers. 0:00000000 1:00000001 2:00000010 3:00000011 4:00000100 5:00000101 6:00000110 7:00000111 The place of each bit starts from the right meaning the the rightmost spot is 2^0. One to the left of that is 2^(1), then 2^(2). If there is a 0 on that spot it means that bit is unused. Now for & wise bit operations. 2&3 is 2 which is greater than 1 which is true because they have one bit in common that's a 1. 2&4 is 0 which evaluates to false because they have no bits in common that are a 1. On the computer system, all numbers are stored in binary notation with 32 bits. Therefore, when you perform an & operation, you & all the bits together. ex. 0 & 0=0 0 &1=0 1&1=1 So when you do &, you really & all 32 bits together. So if you do something like 2&3,you will get 1 b/c they have the 1 bit in common, the one representing the two's place.
