How does && operator work in C?
Accordingly, how does && operator work in C?
Logical AND is denoted by double ampersand characters (&&), it is used to check the combinations of more than one conditions; it is a binary operator – which requires two operands. If both of the operand's values is non-zero (true), Logical AND (&&) operator returns 1 (true), else it returns 0 (false).
Keeping this in consideration, what is difference between & and && in C?
There actually are simple & refers to bit-wise AND and && refers to logical AND in C. Both are binary operators, that means, both need two operands to operate upon. & performs LOGICAL AND operation on binary values of both operands, and outputs value of result of the AND operation.
An operator is a symbol that operates on a value or a variable. For example: + is an operator to perform addition. C has a wide range of operators to perform various operations.
