A commonly used operator classification

1>. Arithmetic Operators

    For processing four arithmetic operations.

2>. Assignment operator

    For the expression of the value assigned to the variable.

3> comparison operators

    For comparison expression, and return a true or false value.

4>. Logical Operators

    It used to return true or false value depending on the value of the expression

5>. Bitwise

    Bit operation for processing data.

6> .sizeof operator

    Length number of bytes used to find.

 

Two arithmetic operators

The term & exemplary results operator 
　+ plus +3. 3 
　- Negative No. -3-3 
　+ 15 plus 10 + 5 
　- Subtraction 10--510 
　* 10 * 550 multiplication 
　/ addition to the 10/52 
　% Whichever modulus (remainder) 10 31% 
　increment ++ before a = 2, b = ++ a ; a = 3; b = 3; 
　increment after 2 = A +, B + A =; =. 3 A; B = 2; 
　- before decrement = 2 A; B = - A; A =. 1; B =. 1; 
　- Save since a = 2; b = a--; a = 1; b = 2;
