If a = 8, find the value of a -= ++a + a++ + 4 - a + 6.

Rewrite the following code using for loop.

int i = 1; 
int d = 5; 
do
{
    d = d * 2;
    System.out.println(d); 
    i++;
} while(i <= 5);

Find out the error(s) in the following code and underlining correct error(s).

int m = 5; n = 10; 
while(n >= 1)
{
    System.out.print("m");
    n--;
}

Evaluate the following expressions, when int a = 8, b = 14.

(a) b/a++

(b) --a + b-- + a
