What is the output of following program?

What is the output of following program?

a++ or a-- is postfix operation, meaning that the value of a will get changed after the evaluation of expression.

++a or --a is prefix operation, meaning that the value of a will get changed before the evaluation of expression.

lets assume this;

a = 4;

b = a++; // first b will be 4, and after this a will be 5

// now a value is 5
c = ++a; // first a will be 6, then 6 will be assigned to c
