Increment and Decrement Operators

                    These Operators are used to control the loops in an effective method.

1. Increment Operator ( ++ ):

                    The symbol ++ is used for incrementing the value by 1.

                    These are Two types

                    i) ++ identifier;    This is also known as prefix increment.

                    ii) identifier ++;    This is also known as postfix increment.

Eg: 

1)  int a=10;  

     ++a; (or) a++; 

     a=11

2)  int a=10,b; 

     b=++a;

     a=11

     b=11 

3)  int a=10,b; 

     b=a++;

     a=11

     b=10

2. Decrement Operator ( -- ):

                    The symbol -- is used for decrementing the value by 1.

                    These are Two types

                    i) -- identifier;    This is also known as prefix decrement.

                    ii) identifier --;    This is also known as postfix decrement.

Eg: 

1)  int a=10;  

     --a; (or) a--; 

     a=9

2)  int a=10,b; 

     b=--a;

     a=9

     b=9 

3)  int a=10,b; 

     b=a--;

     a=9

     b=10
