In prefix operator,the value of the operand increase by one
and then assign the new value to that operand and print
it.In postfix operator,the value of the operand is assigned
at first and then increment it's value by one.
This is the difference between postfix and prefix unary
increment operators.

int j=++i; int j=i++;
cout<<j; cout<<j;
getch(); getch();
} }
OUTPUT:11 OUPUT:10

Answer / bhupender

PER FIX UNARY INCREMENT OPERATION IS ++I
POSTT FIX UNARY INCREMENT OPERATION IS i++
WHEN WE USE THIS IN PROGRAM THE RESULT WILL
FOR ++i IS

LIKE TWO VERIABLE INT A=5 AND B=++A+5 THEN
IN RESULT IT SHOWS A =5 BUT B WILL 10(5+5)
BUT IN POST FIX IT
A=5 BUT B= A++ MEANS A+1 AND RESULT FOR B WILL 11
