Active 5 years, 10 months ago. and the unary -, &, and * operators.) This is called Masking of bits. Bitwise complement operator is used to reverse the bits of an expression. For example, assuming 16-bit integers, ~0x56 is 0xffa9: In c++ what does a tilde “~” before a function name signify? means for int data type this rule will be applicable only for the value of range[-2,147,483,648 to 2,147,483,647]. Best How To : (4) As others have noted, in the instance you are asking about it is the destructor for class Stack. It is a unary operator (taking a single argument) that is borrowed from C, where all data types are just different ways of interpreting bytes. GLOB_TILDE Carry out tilde expansion. The ~ operator in C++ (and other C-like languages like C and Java) performs a bitwise NOT operation  - all the 1 bits in the operand are set to 0 and all the 0 bits in the operand are set to 1. This is the bitwise NOT operator. The following operators perform bitwise or shift operations with operands of the integral numeric types or the char type:. The bitwise complement operator, the tilde, ~, flips every bit. During a casual discussion with one of my friend , I came across a question on whether the tilde(~) symbol can be used in the enum definition as shown below. If the operand to NOT is decimal number then it convert it as binary and perform’s one’s complement operation. The output is 4,294,967,295 and it should be 65,535. These operators are used to manipulate bits of an integer expression. For example: a = 10; b = 20; ch = 'y'; “+=”: This operator is combination of ‘+’ and ‘=’ operators.
