Explanation of Solution
Prefix and postfix mode using Increment operator “++”:
The increment operator is used to increment or increase the value of the variable by “1”.
Example:
/*the variable val is increased by 1 with a postfix representation */
val++;
/*the variable val is increased by 1 with a prefix representation */
++val;
Example :
int x = 5;
System.out.print1n(x++);
In the given program segment, the variable “x” is declared and initialized with the value “5”.
Postfix:
In the println statement, post-increment operation is performed using the statement “x++”. As per postfix mode, the value of the variable “x” is printed and then the value is incremented. Therefore, the value of “x”, which is “5” is printed using the println statement and then the value of “x” is incremented.
Prefix:
int x = 5;
System.out.print1n(++x);
As per prefix mode, the value of the variable incremented by 1 and stores it in the variable “x” and then it is printed. Therefore, the value of “x”, which is “5” is incremented by 1 as “6” and printed using the println statement.
Prefix and postfix mode using decrement operator “--”:
The decrement operator is used to decrement or decrease the value of the variable by “1”...
