Binary operators are the common ones like +, -, /, *, <, >, !=, etc.. These you use with two objects, like : 1 + 2 Unary are the ones that does not need another object, like : ++, +, --, -, ! Like var a = 5; // Not this. this is a assignment a++; //Increment a in one ++a; //Increment a in one a--; // Decrement a in one --a; // Decrement a in one !a; // Logical opposite of a +a; // Positive value of a -a; // Negative value of a

Yes, a unary operator is an operator that only has one operand. Examples of unary operators are negative (-), positive (+), increment (++), decrement (--), address of (&), dereference (*), logical not (!), sizeof, one's complement (~), new, and delete.
No. The subtraction operator is a binary operator that returns the result of subtracting the rhs operand from the lhs operand. The unary minus operator simply negates the rhs operand. int x = -5; // unary minus. x is (-5) int y = -x; // unary minus. y is (+5) y -= x; // binary minus/assign operator. y is (+10) --x; // unary decrement operator. x is (-6) y -= (-x); // binary minus/assign and unary minus operators. y is(+4)
There is no unary plus in C, but if there were, it would have only one operand, unlike the binary plus which has two: x = a + b; /* binary plus */ x = + b; /* unary plus -- not in C*/ x = a - b; /* unary plus */ x = - b; /* unary minus */
