Explanation:
now 'I' variable pointing the base address of the
Array......
1.printf("%d\n",++*I); //I=a[0], bcos I is pointing the
base address. first Increamenting the value so,a[0]=100
become an ( a[0]=101 ).
2.printf("%d"\n,*++I); //This Increment will increment
the address not value. so, now ( I=a[1]=200 ).
3.printf("%d\n",*I--); // now I=a[1]=200 so value will
not change.
4.printf("%d\n",*I); //Now also I=a[1] pointing here only
but a[1]=199, bcos in previous printf after executing we
decrementing the value. a[1]=199......
ANS: a)101,200,200,199
