What are Operators? Explain unary operators with examples.

Answer

Operators:

Symbols that tell the compiler to perform specific tasks/operations.

 Arithmetic Operators:

• Binary
• Unary: ++(Incrementer), --(Decrementer)

++a: Pre incrementer(increment a instantly)

a++:Post incrementer(current value of a is preserved temporarly, a will get incremented before next statement is executed.)

Example:

a=1

b=2

c=3

k=a + b + a++ + b++ + ++c + ++b= 14

  //1   //2   //1     //2        //4        //4
