what is difference between unary operator and binary operator in c++ programming?

A unary operator operates on a single operand while a binary operator operates on a two operands.

For instance, a unary minus simply makes the operand negative. For example, if your operand is 5, a unary minus will make it -5. A binary minus operates on two different operands, subtracting one from another. So if the two operands are 5 and 3, applying a binary minus will result in 5-3 = 2.

Unary '-' : It is used with a single operand and that is why it is an unary operator.Binary '-' : This operator functions upon two operands and returns the difference between the two by subtracting the value of second operand from the first. Both the operands may have float or integer types.
