Test: Programming in C++, C & Java- 2 - Computer Science Engineering (CSE) MCQ

int (*f) (int*);
return type int, (*f) is a pointer to a function the argument is (int*) an integer pointer So, int (*f) (int*) means a pointer to a function that takes an integer pointer as an argument and returns an integer.

The abstract data type (ADT) refers to a programmer defined data type together with a set of operations that can be performed on that data so the choice (c) is correct.

A common property of logic programming languages and functional languages is both are declarative because we declare any statement before we will use it.

Object oriented programming language is Object based PL + Abstraction + Inheritance.
The last two (abstraction and inheritance) are must for any L to be OOPL.

(i) Static scoping facilitate early binding because it is done at compile time.
(ii) Dynamic scoping require late binding because it is done at runt time.
(iii) Early binding increases execution efficiency because both necessary and uncessary things are load at compile time.
(iv) Late binding decrease execution efficiency because only necessary things are loaded when they are needed.

Imperative: C, Fortran 77, Pascal
Object oriented : C + + , Smalltalk, Java
Functional: Lisp
Logic: Prolog

a = (x < y) ? ((x < z) ? x : z) : ((y > z) ? y: z)
In C “ ? is a ternary operator the syntax is (exp1 ? exp2 : exp3). it means if exp1 is true print exp2 else exp3.
Let x = 3, y = 4, z = 2.
⇒ a = (3 > 4) ? ((3 > 2) ? 3 : 2 ) : ((4 > 2) ? 4 : 2) 
a = (3 > 4) ? 3 : 4
a = 4

In the given program it begin from main function, i and j are globally initialized by 0 and 1. So when we call function f(& i, & j) the address of i and j are passed.
when p = q and *p = 2 means
*q = 2, so value of *q is passed. 
and value of *q return to j.
Value of i and j are 0 and 2 respected.
So print i (“ % d % d ”, i, j) gives output (0, 2).

So f(a, 6) → first this call
Thus is the number stored in the array and we can access these by using

P + P[3] - P[1] = 2000 + 69 - 65 
= 2004
⇒ 2011 string will be printed.
(From 2004 Address)

f(50) goes into infinite loop by calling f(i) recursively for i = j = 50.

Therefore the output is 1204

BCPL: Basic Combined Programming Language primary used for system software and called simply B.

"if" is keyword in C not “IF”.
