Using post/prefix increment operator in java program


class apincrement
{
public static void main (String arg[])
{
int a=15,b=34;
int d,e;
d=++a;
e=b++;
System.out.println ("\n\t a = "+a);
System.out.println ("\n\t b = "+b);
System.out.println ("\n\t d = "+d);
System.out.println ("\n\t e = "+e);
}
}


Note:
         When you will execute this program you will see that values of 'a' , 'b' and 'd' are increased by 1 but value of 'e' is same as we initialized it by 34. The reason behind this is we are using post fix increment operator. In case of post fix increment value of the variable is used first and then it is increased by 1.
