Switch ( inchar ) {
case 'A' : printf ("Choice A\ n") ;
case 'B' :
case 'C' : printf (“Choice B”) ;
case 'D' :

Which one of the following are essential features of an object-oriented programming language?
i) Abstraction and encapsulation
ii) Strictly-typedness
iii) Type-safe property coupled with sub-type rule
iv) Polymorphism in the presence of inheritance

An Abstract Data Type (ADT) is

Consider the following C function.

float f,(float x, int y) {
    float p, s; int i;
    for (s=1,p=1,i=1; i < y; i++) {
         p *= x/i;
         s+=p;
    }
return s;
}

For large values of y, the return value of the function f best approximates
