type operator- ();
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 */
A binary function would be one with two parameters, a unary, one with one parameter.However, these words are usually used for operators. For example, the common arithmetic operators, +, -, *, /, % are binary - they need two operands, for example, "2 + 3". The minus sign can also be unary; -x is the additive inverse of x. Unary means one operand is required. Boolean operators for and, or, xor, are binary. Actually, the great majority of operators are binary.

If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
The number of arguments will be one for the unary operators and two for the binary operators. In the case of unary operators, the argument must be of the same type as that of the enclosing class or structure.
#include<iostream> #include<cassert> struct A { int val1; int val2; A (int v1, int v2): val1 (v1), val2 (v2) {} A operator- () const { return A (-val1, -val2); } }; int main() { A a (12, -42); A b = -a; assert (b.val1 42); }
Operator overloading allows you to redefine the functionality of most of the operators, such as + and -. This allows you to create a class that can naturally mimic a native object, such as an integer. Consider a complex number class. Clearly, you would want to overload the basic mathematical operations add, subtract, multiply, and divide, so that a user of your class code could write expressions involving complex numbers without having to think about the implementation details of your class. In the case of other types of classes, for instance a stack class, the meaning of the operators needs to be carefully considered, but it might make sense, for instance, to write a stack push operation as a unary plus, and a pop operation as a unary minus. Certainly, you don't want to go crazy overloading operators just because you can - you want the resulting code to be sensible and readable.
