Assertion (A) next() can read the input only till the space.
Reason (R) next() only gets to the line break.

1. Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
2. Both Assertion (A) and Reason (R) are true and Reason (R) is not a correct explanation of Assertion (A).
3. Assertion (A) is true and Reason (R) is false.
4. Assertion (A) is false and Reason (R) is true.

Write the values of c and d after execution of following code.

int a = 1; 
int b = 2; 
int c; 
int d; 
c = ++b; 
d = a++; 
c++;

Observe the following code and write how many times will the loop execute?

a = 5; 
b = 2;
while(b != 0)
{
    r = a % b; 
    a = b; 
    b = r;
}
System.out.println(" " + a);
