Difference between & and && in C? - Stack Overflow

The & operator performs a bit-wise and operation on its integer operands, producing an integer result. Thus (8 & 4) is (0b00001000 bitand 0b00000100) (using a binary notation that does not exist in standard C, for clarity), which results in 0b00000000 or 0.. The && operator performs a logical and operation on its boolean operands, producing a boolean result.
